PC Controlled Voltage or Current Source


Posted on Jul 20, 2012

This project was begun as a means to charge and cycle NiCad batteries but has become a versatile tool for experiments requiring either a controlled voltage up to +30V and/or a current of +/- 2.5 Amps. If all you want to do is charge and recycle NiCad batteries, then, with hindsight, I`d advise you to buy one of the commerical units available. The circuit I will describe will do the job but it is experimental and has many short comings.
