Re: Quest for the simplest zero voltage switching

Thanks all. I never realized I could get away with a simple RC network
and a zener for DC good enough to drive these ICs. I thought they
would be more particular. I've been looking at electric ranges and
they use what they call an 'infinite' switch. Based on a bimetal on/
off duty cycle caused by a heating element in a wholly mechanical
device. I would feel like I was cheating to use one though. I think
I'll give the solid state method a whirl ! I'm curious why these
inifinte switches have persisted so long. I wouldn't imagine they are
any cheaper than what is being described in this post. Maybe because
of the manufacturing base developed over the years. Are modern ranges
going solid state?
