Dear Members, I am designing 2 KVa pure sine wave inverter system , using SG3525 to step up 24 Dc to 320 Dc , and then using IR2110 to make pure sine wave by SPWM signals from pic16f684 . I have a question that should I Use any optocoupler (like tlp250) between Microcontroller and Driving circuit or should I give signal directly to IR2110. (plz suggest so that will there be any problem when inductive load is connected ). plz help
