    Testing neutral-to-ground voltage of switching mode power supplies

    I am attempting to create a sine wave signal from 0V to 12V at 40 Hz and up to 1.4A, with original power input 120VAC 60 Hz wall power. I've come up with the circuit below, which I'm pretty sure works in theory but the implementation is not working. I can get the correct high voltage (12V) at...
