This circuit will not work unless the 230v is from a transformer winding that is floating. the standard AC mains has the neutral earthed at the supply transformer and is always close to earth, i.e. 0 -> 6V AC, depending on the total supply current from that supply transformer. Also as the earth current is equal to the output current , this (...)

I have a 230v to 15V-0-15V step down transformer without the center tap wire. Is it okay to just insert the wire in the hole (middle one) to make it work ? I have to use the 0V connection in the circuit from the transformer.
Any suggestion ?

I am trying to implement 0-230v variable voltage control to my high voltage power supply. I am using a ceiling fan regulator to do the same. But I am not able to control the voltage. When I keep the regulator in off position, I am able to keep the power supply to the module switched off. However, when I turn on the knob, the (...)
