Power supply circuit diagram

Variable Power Supply 0-30V_10A using dual 2N3055 transistors, LM317, BD139, A/V Meter and two Potentiometers to control amperes & volts.

I am pretty new to SMPS circuits. I understand there's a bleeder resistor, a flyback diode circuit to power the transistorized osc circuit. I guess that the current around the MOSFET will be like a...

Transformerless Power Supply (220V AC to 14V DC) circuit + pcb

Build a Bench top lab power supply that is capable of delivering 0 to 50 volts and 0 to 5 amp or A to the load. This electronic project can serve as a your lab power supply to test and power your experiments. With the variable supply feature, it is easy to control and deliver voltage and current to the load.
