My coutroller is not 100% finished it's more like 89%
You are building your controller with microcontroller for brain ? Are you planing to put temp. monitoring and stuff like this or is it just for the PWM ?
The main diferent between your and mine is that mine is made with just ~100$. It's cheap and very simple , it's based on SG3525 ( for PWM ) , bd139/140 ( for sig.amp. ) , irfp450 ( for power grup x6 ) and for dides byv72ew200 x4 .
In a video it didn't have capacitor ( only one from power supply ) I'm putting few in there ! All electronics are electricaly isolated from the aluminiun box but they aren't thermal isolated !!
