Hi folks.
I am trying to put together Bill Bowden's thermostat circuit to
trigger back-to-back SCRs to turn on a water heater element run on
120v (to make a 500 watt heater).
I don't have a 3 winding trigger transformer laying around, but I do
have a nice toroid core I picked up surplus that is supposedly for
pulse transformer use. Can I just wind a trifilar winding around it
with some 28AWG magnet wire and have half a chance it will work? The
core measures about 2 uh with 8 turns on it, so I figure it is a
pretty low mu ferrite core.
TIA.
