Hi there
I'm building a hex bridge for a 230VAC induction motor controller for PWM and I can't get the right MOSFETs (very expensive) so I was thinking of IGBTs. I'm new to IGBTs so could someone provide me a circuit that shows how to turn them on and off with TTL or CMOS signals (PICs)?
Are SCRs better or are they too slow switching?
(A circuit for that if it's better)
Thanks
