Is true pulse width modulation control of AC current feasible without worrying about the phase of the AC current?
I would like to use an arduino to control SSRs to regulate heat in my HLT with heat element. Let's just say I want the element to be producing 50% heat. I know that I can program the arduino to cycle the SSR on 2 sec, off 2 sec. This gives me a psuedo pwm effect. If I were to send a 50% pulse train at the arduino's ~500Hz, what would be the effect? This would give an on pulse for about 1millisec the off for about 1millisec. Would I get a 50% reduction in power or would the 500Hz pulse matching with 60Hz AC give me problems?
I'm a mechanical engineer, I know just enough about electricity to make me dangerous.
