In the video below, the power supply is set up, short circuit tests, load tests, notes, etc.
#Ltspice ac source for mains voltage Pc
Normally, it is not necessary, but there was no suitable cooler, it was setup for the test ( PCB drawing was prepared for the output transistors).īy combining the outputs of the 0.22 OHM 5W equalization resistors, a single thick cable, wire can be used, I used a pull-out resistor, the legs were short, I did not make any additions, I used the cables I disconnected from the pc power supply. continuous / 1OA Max.įor the 2SC5200 output transistors, I made all the connections with a separate cable. LM741 opamp is used for AC voltage stabilization.Īdjustable output voltage from 0v to 30V.Īdjustable output current from 0v to 10A. In this design, separate LM723 is used for voltage and current part. The regulated power supply is based on 2 LM723 (UC723), normally LM723 can control current and voltage by itself.
I installed DC rectifier, filter, relay stage with direct cables (I prepared PCB for these parts of the circuit) 0-30V 0-10A Power Supply Circuit Diagram Since I have a toroidal transformer with an estimated voltage of 250W…300W 2X15VAC, I did the tests with it, and the normal sheet transformer can also have a usable power of at least 300W or more. Actually, I implemented the power supply circuit with limited possibilities, but it is sufficient for me, the first tests were done successfully.
