Am citit cartea propusa in link, topologia mea e punte in punte out, nu prea pot folosi snubbere cu inductor,

Cu 4 sic mosfet de 20 miliohm la 900v cu cate o dioda sic schottky in paralel alimentat la 120v duce 3 kw fara snubbere cu frecventa de comutare de 50 khz, si 5 kw surge 1 secunda, destul de bine  pentru tranzistoarele alea, dar nu prea rezista la scurt pana se pune protectia, am vazut ca folosind snubbere  rezista mai bine la scurt, presupun ca o mica inductanta in serie chiar si proprie rezistentei reduce stressul on tranzistor at turn on, dar inrautateste prestatia at turn off.

Probabil trebuie  un trade off intre cele doua aspecte.
