An applied project belonging to Elektor magazine. Digital power supply This project is a power supply modification published by Osvaldo Valdorre’s elektor…

TDA8138 Two Channel Multi Regulator Circuit 5V 12V

| 2009/02/15

TDA8138 Two Channel Regulator Circuit PCB printed circuit and schematic drawing of TDA8138 datasheet application prepared with eagle cad electronic drawing program. I used to wonder why they wouldn’t do this type of multi-output IC from time to time, but it wasn’t very popular or it didn’t come across to me.. TDA8138 features; Output current…

Voltage Current Regulated 2N3055 LM723 Power Supply

| 2009/01/18

Modification of the LM723 2N3055 stabilized power supply. I have always been concerned that the voltage drop is large when a load is applied and this is clearly visible even with a 30V voltmeter. (After adjusting the voltage with no load, 100 to 200mV drops when 3 to 4A load is applied) In particular, when…

High Voltage Laboratory Power Supply Circuit 50V to 450V 500mA

| 2008/10/27

High Voltage Laboratory Power Supply. The power supply we offer provides an adjustable voltage from 50 to 450 Volts at a current of 500 milliamps with 0.1% resolution. Residual ripple and noise value at 100Hz: <1 mV pp over the entire range. Internal resistance is < 0.5 Ω static and < 1 Ω dynamic from…

2.5v – 27.5v 2Amp Laboratory Power Supply Circuit

| 2008/10/23

The laboratory power supply circuit is similar to the classical transistor power supplies, the mosfet irfp150 is used as a power transistor, the author has placed the circuit in the pc power supply box, added a volt meter module, and a toroid transformer is used in the circuit, which can be used in normal sheet…

Very strong power supply high power devices circuit to run the ideal voltage and current settings accurately can be done over-heat protection temperature fan control features used power transistors tip142 npn darlington toroid transformer used this transformer lighter and becomes more efficient, but the prices are high normal hair transformer used in 0-30V 0-10A Power…

Adjustable voltage and current power supply LM337 LM317

| 2008/09/07

LM317 (positive voltage regulator) and LM337 (negative voltage regulator) output series-connected power transistors powered by the 5k and 20k potentiometer binary (stereo) type if you use the + and – output of the current and voltage settings set equal can Show some circuits and found that the output resistance of between 200 ~ 240 I…

Simple Symmetric Power Supply Circuit with LM317T LM337T

| 2008/09/04

The power supply circuit has a simple design, but it is a useful circuit that you can use in various circuit tests using 2 LM317T Positive regulators and 2 LM337T Negative voltage regulators. The output voltage can be adjusted gradually with the commutator. In fact, the voltage range can be adjusted more precisely with the…

LM317T Adjustable Regulated Power Supply

| 2008/09/01

The circuit has 1 ampere power adjustable between 1.3…22 volts, normally lm317t 1.2..32 volt adjustable can be used for some reason. If r2 is canceled and 5k is used instead of 2k trimpot, a simple 32 volt adjustable power supply circuit can be used to operate low current circuits. Do not use without a cooler.…
