Re: Rectified wave problem
looks like your ac signal earth reference is biased one forward diode voltage above earth.
you need something like this

Re: Rectified wave problem
I use 'ac opto' to get 0xing. vary R3 to change width of the zero areaAttachment 7388
oh, add series resister to opto input !!

Re: Rectified wave problem
thought that was part of your power supply stuff !! otherwise then not needed.
