Dual Adjustable Power Supply
This project is a solution to power up most of devices or projects requiring dual (+/-) adjustable power supply.
9V to 48V DC-DC Converter
This project is a 8-12Vdc to +48Vdc DC-DC converter based on MC34063 switching regulator.
0-30V Laboratory Power Supply
This project is based on the 0-30 VDC Stabilized Power Supply with Current Control 0.002-3 A and a new PCB layout is introduced here.
Variable Power Supply with LM7812
This project is a simple variable power supply using the famous LM7812 regulator IC.
MCU Controlled Spot Welder
This project is a controller for a dual pulse spot welder that has some nice features that are controlled using a LCD interface.
Digital Multiple Voltage Power Supply
1.2 to 33 Volts DC @ 3 Amps Description This is simple to build microcontroller controlled power supply that can switch between 5 (or 32 or more) preconfigured voltages between 1.2 to 33 volts dc and up to 3 amps.
Mini variable power supply
Description T1 steps down AC voltage from 115VAC (or 220VAC) to about 8VAC and is then rectified via bridge rectifier BR1 to about 11.52Vdc.
