hI,
I am using a 3Hp DC motor at 3 phase AC electic with 6 numbers of Thyristors.Now I need a speed control circuit and protection circuit with a Micro.Anybody have a idea or Net Can I find a similar circuit?
 

i think u need dac(digital to analog converter) for this action. u can fed binary output in dac from microcontroler & dac out analog voltage according your binary. these analog votage applied in 3 IGBT,s gates for variable speed.
 

I think PWM will do.So any circuit or link?
