transformer Single pole AC to DC conversion circuit


Posted on Feb 4, 2014

A remote control light switch that fits into the existing light switch panel. And to power up the electronics that would requires a 3. 3V DC supply. The problem is, the panel has only two wires inside - 1. Live and 2. wires that goes to the light bulb. The neutral lines is not routed through the panel box. The capacitor got charged by the positive and negative cycle, I suppose.

But I want a continuous supply of DC for the microcontroller/radio, I am not sure how to modify that.
