I'm controlling a resisitive heating element in an oven. I think you misunderstand my question. I don't mean sustaining the repetition of pulses, I mean actually sustaining single, long pulse so that it holds the triac gate high through 100% of the conduction time, rather than sending a trigger pulse after every zero crossing.
I know all is needed is a quick trigger pulse at the beginning of each half cycle, but what if I extended this pulse to be on throughout the ENTIRE half cycle(s). Is there some problem with this simpler, less efficient approach that I am not aware of? (Everyone seems to use repeating burst pulses after the zero cross. No one, and I mean no one seems to just bridge all the pulses together to make a long pulse that is always on throughout the half-cycles).
