Dear All,
We have rectifier circuit that using only RC ( R=47ohm 10W, C=220n F 1600V PILKOR 378 MKP/MKP ). Input is 380VAC/3phase then output is VDC. How does that work ? I have tried with principle of snubber in the EWB, but it can not show that the voltage out is DC.
Maybe you can help me, how the RC circuit can rectify the AC voltage ?
Thank's

Please post the schematic. It' s difficult to help without seeing exactly what you're doing.

I was tried the circuit, and replace Resistor with 47 ohm/15W because it was broken when the circuit was explode. And then output voltage AC, about 1.73 VAC.
This attachment may be explained illustrations.
Thanks.
