Bad Alternator Diode causing transmission/speedometer problems

Speedometer reads 20 mph in park. Transmission output speed sensor (vehicle speed sensor) codes. Transmission will not shift (2nd gear limp mode) from a bad alternator diode.

Halfwave Rectifier Experiment | How the connections are made | Finding the ripple factor
 
01:42
Here described how the connections are made for finding the ripple facor of a halfwave rectifier. We need a step down transformer, resistors, capacitor, bread board, digital multimeter, and a power supply 1.A rectifier is a circuit which converts the Alternating Current (AC) input power into a Direct Current (DC) output power. The input power supply may be either a single-phase or a multi-phase supply with the simplest of all the rectifier circuits being that of the Half Wave Rectifier. 2.A widely used application of this feature and diodes in general is in the conversion of an alternating voltage ( AC ) into a continuous voltage ( DC ). In other words, Rectification. But small signal diodes can also be used as rectifiers in low-power, low current (less than 1-amp) rectifiers or applications, but where larger forward bias currents or higher reverse bias blocking voltages are involved the PN junction of a small signal diode would eventually overheat and melt so larger more robust Power Diodes are used instead. The power semiconductor diode, known simply as the Power Diode, has a much larger PN junction area compared to its smaller signal diode cousin, resulting in a high forward current capability of up to several hundred amps (KA) and a reverse blocking voltage of up to several thousand volts (KV). Since the power diode has a large PN junction, it is not suitable for high frequency applications above 1MHz, but special and expensive high frequency, high current diodes are available. For high frequency rectifier applications Schottky Diodes are generally used because of their short reverse recovery time and low voltage drop in their forward bias condition. Power diodes provide uncontrolled rectification of power and are used in applications such as battery charging and DC power supplies as well as AC rectifiers and inverters. Due to their high current and voltage characteristics they can also be used as free-wheeling diodes and snubber networks. Power diodes are designed to have a forward “ON” resistance of fractions of an Ohm while their reverse blocking resistance is in the mega-Ohms range. Some of the larger value power diodes are designed to be “stud mounted” onto heatsinks reducing their thermal resistance to between 0.1 to 1oC/Watt. If an alternating voltage is applied across a power diode, during the positive half cycle the diode will conduct passing current and during the negative half cycle the diode will not conduct blocking the flow of current. Then conduction through the power diode only occurs during the positive half cycle and is therefore unidirectional i.e. DC as shown. 3. Half Wave Rectification A rectifier is a circuit which converts the Alternating Current (AC) input power into a Direct Current (DC) output power. The input power supply may be either a single-phase or a multi-phase supply with the simplest of all the rectifier circuits being that of the Half Wave Rectifier. The power diode in a half wave rectifier circuit passes just one half of each complete sine wave of the AC supply in order to convert it into a DC supply. Then this type of circuit is called a “half-wave” rectifier because it passes only half of the incoming AC power supply as shown below. 4. During each “positive” half cycle of the AC sine wave, the diode is forward biased as the anode is positive with respect to the cathode resulting in current flowing through the diode. Since the DC load is resistive (resistor, R), the current flowing in the load resistor is therefore proportional to the voltage (Ohm´s Law), and the voltage across the load resistor will therefore be the same as the supply voltage, Vs (minus Vf), that is the “DC” voltage across the load is sinusoidal for the first half cycle only so Vout = Vs. During each “negative” half cycle of the AC sinusoidal input waveform, the diode is reverse biased as the anode is negative with respect to the cathode. Therefore, NO current flows through the diode or circuit. Then in the negative half cycle of the supply, no current flows in the load resistor as no voltage appears across it so therefore, Vout = 0. The current on the DC side of the circuit flows in one direction only making the circuit Unidirectional. As the load resistor receives from the diode a positive half of the waveform, zero volts, a positive half of the waveform, zero volts, etc, the value of this irregular voltage would be equal in value to an equivalent DC voltage of 0.318 x Vmax of the input sinusoidal waveform or 0.45 x Vrms of the input sinusoidal waveform. Then the equivalent DC voltage, VDC across the load resistor is calculated as follows.

Experiment #5 - Full Wave Carbon Fibre HHO Bridge Rectifier Demonstration
 
11:39
A demonstration of my new full wave bridge rectifier producing HHO in considerably larger quantities. This new rectifier requires only two standard diodes to produce a 12VDC output with a ripple voltage of less than 1V. This circuit consumes approximately 100 Watts from a 240VAC mains power supply. Power consumption is determined by three things: 1. Conductivity of the water/amount of electrolyte (electrolyte is optional) 2. Frequency of the AC input signal. 3. Total surface area of the electrodes producing the HHO. I will conduct further experiments with various high frequency AC input signals (including modified sine waves) to see if HHO production can be increased.

find out a choke coil for a DC power supply on 50/60 Hz or other freq. (basics)
 
08:49
MORE INFO&LINKS IN THIS TEXTBOX. WARNING: some oscilloscopes can NOT handle 300 Volt at their input. These scopes will immediately be defective! So read the manual from your oscilloscope to find out the maximum input voltage on the probe! When it is low, use a voltage divider at the output from the circuit (1 M- 10K) and connect the probe from the scope at the node -low voltage point- from the voltage divider). This video (somewhat too long, sorry, I repeat myself too much) shows how you can find out a choke coil in a PI filter configuration that damps out the 50 Hz or 60 Hz from the standard mains supply in Europe, US, elsewhere. Value from 50 uF relates to 50 Hz or 60 Hz systems. Succes in a real/concrete situation depends on experiments (!) with old /unused/thrownaway ferrite core coils or old transformers (iron lamellae cores) in the 10 Watt range made for 110 V or 230 V 50 Hz or 60 Hz AC.With simple resources, e.g. the old AC 230V- 110 V AC transformers, self-wound coils on a ferrite rod, old computer power supply filter coils, etc, can be used . You must find it all out (oscilloscope absolutely necessary). With the oscillator you can get an indication about the healthyness and usefulness of old (ferrite core or not) coils. NEVER connect your oscilloscope directly to 100 - 300 V or more (!!). Keep in mind that on power supplies on higher frequencies (40 KHz - 400 KHz) the choke coil and the caps from the Pi filter have to be adapted to the high frequency. In that case no electrolytic capacitors must be used but only non polar plastic caps or ceramic caps (low HF loss). More circuits in my books on the Lulu website, author Ko Tilman, or on the internet. The video that I refer to in this video is: "test oscillator for coils 30 mH-3,6 uH (0,9uH) (e.g.25 KHz-1,2 MHz" published 10 october 2014 BUT (!) Better/also usable are: 1. "FET test oscillator sine wave with very good linearity (200 KHz - 9 MHz)" published 3 october 2015 2. "Device to test radio coils on resonance, optimum frequency and quality" published 25 october 2015. Both circuits are usable. The oscillator published on 25 october 2015 is somewhat more sophisticated (has a broader frequency band, especially on lower frequencies, say 35 KHz - 200 KHz).

Simple Diode Protection Circuits in Rectifiers ...
 
02:02
Simple Diode Protection Circuits in Rectifiers of Transformer Power Supply Sources As a rule build-up of filter capacitors are used in order to bring the voltage ripple level in transformer power supply units to as low as possible. This is not the most efficient method, as at the time of connection the uncharged filter capacitors as a whole act as the short circuit for the rectifier diodes and the secondary transformer winding. To limit the charge current of the filter capacitors, constructors often use current-limiting components that in the majority of cases get disconnected automatically. One of the examples here is the parallel rectifier diode protection circuit, where capacitance 1 is connected in series to the resettable fuse. The second option is the series diode protection circuit. In this case capacitors 1 and 2 are separated by the resettable fuse. As result of the current pulse, these protection fuses temporarily disconnect the entire capacitors circuit, and then connect again in a certain amount of time. The third circuit is diode protection at connection. Here a current-limiting resistor is added between the diodes and the filter capacitors. Mounted in parallel to the resistor is a resettable fuse that is designed for the maximum current flowing through the rectifier diodes. With a pulse of the charge current, the fuse resistance increases, and the capacitors get gradually charged through the current-limiting resistor. Later the resistance of the fuse decreases. At the same time, resetting fuses protect the rectifier elements from overcurrent and short circuits.

The reactance (X) of the capacitor (C) in the mains frequency (f) can be calculated using the formula: X = 1 / (2 ¶ fC ) For example the reactance of a 0.33µF capacitor running in the mains frequency 50Hz will be: X = 1 / {2 ¶ x 50 x 0.33 x( 1 / 1,000,000) } =9645.75 Ohms 0r 96.6 Kilo ohms. Rectance of the capacitor 0.33 uF is calculated as X = 1/2Pi*f*C Where f is the 50 Hz frequency of mains and C is the value of capacitor in Farads. That is 1 microfarad is 1/1,000,000 farads. Hence 0.33 microfarad is 0.33 x 1/1,000,000 farads. Therefore the rectance of the capacitor appears as 9645.75 Ohms 0r 96.6 Kilo ohms..To get current I divide mains Volt by the rectance in kilo ohm.That is 230 / 96.6 = 23.80 mA. Effective impedance (Z) of the capacitor is determined by taking the load resistance (R) as an important parameter. Impedance can be calculated using the formula: Z = √ R + X Suppose the current in the circuit is I and Mains voltage is V then the equation appears like: I = V / X The final equation thus becomes: I = 230 V / 96.6 = 23.80 mA. Therefore if a 0.33 uF capacitor rated for 230 V is used, it can deliver around 23 mA current to the circuit. But this is not sufficient for many circuits. Therefore it is recommended to use a 470 nF capacitor rated for 400 V for such circuits to give required current. X Rated AC capacitors – 250V, 400V, 680V AC x rated ac capacitors Table showing the X rated capacitor types and the output voltage and current without load capacitor and current Rectification Diodes used for rectification should have sufficient Peak inverse voltage (PIV). The peak inverse voltage is the maximum voltage a diode can withstand when it is reverse biased. 1N4001 diode can withstand up to 50 Volts and 1N4007 has a toleration of 1000 Volts. The important characteristics of general purpose rectifier diodes are given in the table. DC Smoothing A Smoothing Capacitor is used to generate ripple free DC. Smoothing capacitor is also called Filter capacitor and its function is to convert half wave / full wave output of the rectifier into smooth DC The capacitance value determines the amount of ripples that appear in the DC output when the load takes current. Voltage Regulation Zener diode is used to generate a regulated DC output. A Zener diode is designed to operate in the reverse breakdown region. If a silicon diode is reverse biased, a point reached where its reverse current suddenly increases. The value of R can be calculated using the formula: R = Vin – Vz / Iz Where Vin is the input voltage, Vz output voltage and Iz current through the Zener In most circuits, Iz is kept as low as 5mA. If the supply voltage is 18V, the voltage that is to be dropped across R to get 12V output is 6volts. If the maximum Zener current allowed is 100 mA, then R will pass the maximum desired output current plus 5 mA . So the value of R appears as: R = 18 – 12 / 105 mA = 6 / 105 x 1000 = 57 ohms Power rating of the Zener is also an important factor to be considered while selecting the Zener diode. According to the formula P = IV. P is the power in watts, I current in Amps and V, the voltage. So the maximum power dissipation that can be allowed in a Zener is the Zener voltage multiplied by the current flowing through it. For example, if a 12V Zener passes 12 V DC and 100 mA current, its power dissipation will be 1.2 Watts. So a Zener diode rated 1.3W should be used. The drawback of the Capacitor power supply includes No galvanic isolation from Mains.So if the power supply section fails, it can harm the gadget. Low current output. With a Capacitor power supply. Maximum output current available will be 100 mA or less.So it is not ideal to run heavy current inductive loads. Output voltage and current will not be stable if the AC input varies.

While testing components for my laser communicator series, my old Radio Shack power supply died. So what's next? An autopsy on video of course. First, we speculate about what could cause the symptoms (full unregulated voltage on the output--23 volts on a 12-volt power supply). Then we check some voltages and see what actually happened. We also compare its circuit to the circuit in my linear power supply series. Dave Jones from EEVBlog makes a guest appearance to help analyze the circuit.

how to design a mobile charger circuit  in multisim software
 
11:44
how to design a mobile charger circuit in multisim software his circuit mainly consists a step down Transformer, a Full wave bridge rectifier and a 5V voltage regulator IC (7805). We can divide this circuit into four parts: (1) Step down AC voltage (2) Rectification (3) Filtration (4) Voltage Regulation. 1. Step down AC voltage As we are converting 220V AC into a 5V DC, first we need a step-down transformer to reduce such high voltage. Here we have used 9-0-9 1A step-down transformer, which convert 220V AC to 9V AC. In transformer there are primary and secondary coils which step up or step down the voltage according to the no of turn in the coils. Selection of proper transformer is very important. Current rating depends upon the Current requirement of Load circuit (circuit which will use the generate DC). The voltage rating should be more than the required voltage. Means if we need 5V DC, transformer should at least have a rating of 7V, because voltage regulator IC 7805 at least need 2V more i.e. 7V to provide a 5V voltage. 2. Rectification Rectification is the process of removing the negative part of the Alternate Current (AC), hence producing the partial DC. This can be achieved by using 4 diodes. Diodes only allow current to flow in one direction. In first half cycle of AC diode D2 & D3 are forward biased and D1 and D4 are reversed biased, and in the second half cycle (negative half) Diode D1 and D4 are forward biased and D2 and D3 are reversed biased. This Combination converts the negative half cycle into positive. full wave rectifier A full wave bridge rectifier component is available in the market, which consist that combination of 4 diode internally. Here we have used this component. Full Wave Bridge Rectifier 3. Filtration The output after the Rectification is not a proper DC, it is oscillation output and has a very high ripple factor. We don’t need that pulsating output, for this we use Capacitor. Capacitor charge till the waveform goes to its peak and discharge into Load circuit when waveform goes low. So when output is going low, capacitor maintains the proper voltage supply into the Load circuit, hence creating the DC. Now how the value of this filter capacitor should be calculated. Here is the formulae: C = I * t / V C= capacitance to be calculated I= Max output current (let’s say 500mA) t= 10ms, We will get wave of 100Hz frequency after converting 50Hz AC into DC, through full wave bridge rectifier. As the negative part of the pulse is converted into positive, one pulse will be counted two. So the Time period will be 1/100= .01 Second= 10ms V = Peak voltage – voltage given to voltage regulator IC (+2 more than rated means 5+2=7) 9-0-9 is the RMS value of transforms so peak voltage is Vrms * 1.414= 9* 1.414= 12.73v Now 1.4v will be dropped on 2 diodes (0.7 per diode) as 2 will be forward biased for half wave. So 12.73 – 1.4 = 11.33v When capacitor discharges into load circuit, it must provide 7v to 7805 IC to work so finally V is: V = 11.33 – 7= 4.33v So now C = I * t / V C = 500mA * 10ms / 4.33 = .5 * .01 / 4.33 = 1154uF ~ 1000uF filteration 4. Voltage Regulation A voltage regulator IC 7805 is used to provide a regulated 5v DC. Input voltage should be 2volts more than the rated output voltage for proper working of IC, means at least 7v is needed, although it can operate in input voltage range of 7-20V. Voltage regulators have all the circuitry inside it to provide a proper regulated DC. Capacitor of 0.01uF should be connected to the output of the 7805 to eliminate the noise, produced by transient changes in voltage. Voltage Regulator 7805 Pins regulation Here is the complete circuit diagram for cell phone charger circuit: Cell Phone Charger Circuit Diagram You need to be very careful while building this circuit, as AC mains 220V is involved here.

Semi automatic 12 V lead acid battery charger electronic circuit
 
06:26
Important: read the textbox before you want to make or experiment with the circuit. CORRECTION to the schematic: the 3K3 resistor must be 33K (=33000 Ohm!). SORRY for that! 1. The circuit is made for lead acid batteries (open or closed, small or big capacity, this depends on the max current that the 12 V relay can handle). The circuit is also useful for nickel cadmium or manganese hydride cells. Read the datasheet from the lead acid battery to get a good insight about the maximum charge current and voltage that your battery needs. This can vary, due to the type of the lead acid battery. 2. The circuit is NOT developed for lithium or polymer batteries (danger of scorch/fire or even explosion)! So don’t use it for that aim, there is real danger. 3. When you add a normal silicon diode in the row, the switch-off voltage gets higher. When you take away a normal silicon diode out of the row, the switch off voltage gets lower 4. The circuit switches on 1/100 of a Volt. This means that you need a digital voltmeter over your (car) battery (in a test situation) with two digits behind the comma to get a good insight about how the voltage switch acts/reacts and to tune it to the right switch-off voltage 5. The Silicon diode A to the 12 V (car) battery must be able to handle the charge current. It will surely get warm or hot on charge currents higher than 2 Ampère. Use a heatsink if necessary or use the diodes from a metal bridge rectifier on a heatsink when a high charge current has to flow (say 5 Ampère or more). This diode prevents that your battery starts to drain out its energy to the electronics when the power supply is switched off. 6. When the battery is fully charged it must be disconnected (!) from the electronic circuit/the voltage switch. The circuit is not made to keep a battery constantly under charge, e.g. like in an alarm system. During the time (weeks, months) the battery will loose its charge and when it is under-voltaged it will damage itself. So after approx. 2 months or so the battery must be charged anew. 7. To start the charge process: switch the mains switch on so that the voltage to the circuit rises from 0 Volt to the charge voltage that is needed for the application. When you add suddenly 14 Volt or more to the electronics it will not work because the switch detects that voltage as “too high” and does not switch on. 8. The electrolytic capacitor in the voltage supply must have a value from 4700 uF or higher (10000 uF). Reason: it could be that the circuit does not work properly when there is hum/ripple from the AC transformer on the DC voltage. That 4700 uF or 10000 uF electrolytic cap must be bridged wit a foil cap from 100 N (O,1 uF at say 300 V) and a resistor from 1 M (1 Mega Ohm= 1 million Ohms or a resistor from 500 K = five hundred thousand Ohms). They all have the purpose to stabilize the supply voltage for sensitive electronic switch circuits like this. When ripple voltage is present it could be that it does not switch exactly. E.G. use a 4700 uF or 10000 uF cap.

When my video’s are reproduced or re-edited on other websites/channels you cannot be sure about the original content (=really working electronics) and important adaptations to the circuits. For a comparable electronic circuit watch: https://youtu.be/y6rtlidSo4w I changed the 27 Ohm resistor from that earlier schematic to 470 Ohm to protect the end-transistor (BD 139) better for a too high base current.

How to make a full wave bridge rectifier
 
04:13
Description = Power Diodes can be connected together to form a full wave rectifier that convert AC voltage into pulsating DC voltage for use in power supplies. In the previous Power Diodes tutorial we discussed ways of reducing the ripple or voltage variations on a direct DC voltage by connecting smoothing capacitors across the load resistance. While this method may be suitable for low power applications it is unsuitable to applications which need a “steady and smooth” DC supply voltage. One method to improve on this is to use every half-cycle of the input voltage instead of every other half-cycle. The circuit which allows us to do this is called a Full Wave Rectifier.
