Why is it that pulse proportional thermostats can't be used on globes? I would assume that they are simply pulse width modulated which runs at a certain frequency, maybe 50-100hz and in each cycle of that frequency, it turns on for one part and turns off for another, say 60% on 40% off for example and varies that on/off ratio to maintain the desired temp. So the the globe is turned on and off 50-100 times per second, being on for 60% of each one of those 50-100 times.
Is this not similar to simple AC current? AC current runs at 50hz and that voltage runs up to 240V and back to 0V and then runs current in the opposite direction to 240V (actually I think it's somewhat higher than 240V as the 240V is the mean average or something like that) than back to 0V so essentially it is still turning on and off 50 times a second.
I guess we are amplifying and amplified current in a way and if the pulse proportional thermostat is turning on when the supplied current from the wall is peaking, then we would spike the filament in the globe and blow it?
Sorry, I guess I'm trying to understand it all a bit more as I'm an auto electrician so I don't work with AC as much but I like to learn as much as I can and am fascinated by electricity and electronic components and how they work. Also, I am not saying it should work, I understand it has been tried before and failed but I'm trying to understand why.
