I'm trying to drive a Peltier cell. The driver must allow both operation modes (cold/hot). To achieve this i'm using filtered 3.3V 100KHz PWM from a microcontroller to drive an H-Bridge (as far as i've read on the internet filtering PWM signals coming out from the bridge with an LC filter is useful for efficiency problems). The Peltier cell is a 70W 12V module.
I'd like to know if this circuit will likely work or if there are any mistakes in components maximum ratings (like free-wheeling diodes) or other stuff that can create magic white smoke.
Feel free to ask anything.
