So last year i decided to build some Christmas lights and a controller.
Now stupidly forgot to check the voltage rating of the mosfets i was using (had them sat around for a few years) and decided to put 230v dc across them, and ofcourse they didn't last long
Roll on a year later and i want to actually use the controller but can't decide between an IGBT or Mosfet, and whats best to drive them as everything thats logic level i can find isn't going to work with the high voltage.
Would be great to know what others have used to control a 230v dc with PWM.
By the way i'm an electrician and play with mains electricity on a daily basis so not worried about the whole you shouldn't be doing this
Cheers
Normally an SSR is the choice to control mains with logic levels.
The only advantage of IGBT is the voltage rating. Mosfets are always superior in every other way.
Fair enough, an SSR isn't really going to be suitable for PWM though is it?
So you'd think i'd be better off driving a 600v mosfet? cheers
If you already have the zero-crossing worked out then use the MOSFET.
