I'm trying to design a Transformer Less power supply as the circuit below,
by measuring the voltage at the capacitor with AVO in ac mode i got 220V,but by measuring the input of the regulator with AVO in dc mode i got 0V all measuring at no load, and
i don't know why i got 0V at the i/p of the regulator ?
although i connected the same circuit with load resistance 2.2K Ohm and without the regulator i got 1.3V as load voltage
also i'm confused in another thing,
the output of the diode is not a pure DC since it's half sin wave changed in value and not a direction
should i measure it with an AVO in DC mode or AC mode ?
thanks
