I need a Sch. to a Build a Variable (Voltage & Amp), 36 Volt / 25 or 30 Amp Pwr Supply.

I have a Microwave Transformer, that I Removed the Secondary Winding, ( 600 Amps ),
I can Increase or Decrease the Winding for Voltage Output.

I have several Sch. to build Pwr Supply's, but I don't Know how to build one
that I can Adjust the Amperage Up or Down ( 0 Amp to 30 Amps ).......

I needs to be Cheap & Dirty / Not High Tech....

I don't what to Buy One, There is No Challenge on that...

Can anybody Help ???

 

Unfortunately variable voltage and current capability from a microwave oven transformer based circuit is going to be neither cheap or simple.

More importantly what are you powering? That is what will dictate the design of the power supply.

 

Microwave transformers are no good for psus, they maybe high current but the voltage will be low, or high voltage with low current, your better getting switch mode psu, you wont make one cheaper than ready made.
