Variable DC Power Supply 0 - 1000 V


This is a home-made AC-to-DC power supply to drive the electrolysis cell. The big thing at the bottom is a Variac I found, then there's a step-up transformer on the right, and a capacitor array which acts as a smoothing capacitor. Capacitor array is 3,000 uF rated at 400 V DC. Transformer is 120 to 12 V wired up backwards. Hopefully it won't blow out. Variac is 0 - 135 V. Oh and of course there's a full-wave rectifier in there.

I'll post a schematic soon.

  1. Hey. I am doing my project on plasma electrolysis. I have really big difficulties understanding electronics, speccially variac and auto-trasnformer part. Can you help me please?
