| Apr 14, 2015 at 2:54 | comment | added | AaronD | Hmm...okay, I think I know what you're doing here. You're selectively half-wave rectifying the mains into your coil to produce the desired polarity, correct? Because you might be able to adapt a more traditional "light-dimmer" circuit to do that, as in my answer here: electronics.stackexchange.com/questions/148078/… However, you'll need to add a snubber (resistor+capacitor in series) across the power triac to try and prevent the false triggers as described in my notes over there. Did I read you correctly? | |
