half controlled rectifier using scr
I want to design a half controlled SCR rectifier with PIC16f877 for driving a 15kW DC motor. is it possible? what do you suggest me to do? I have problems about firing thyristor and turning them off. they are not GTOs. I found TCA785 IC for single phase half controlled rectifier control. is it a good choice? what is the other possibilities? Should I use pulse transformer or MOC3021/51? Is there a sample circuit? for 15kW dc motor,at the end of the positive cycle, does thyritor turn off by self commutation or should I use forced commutation?
thanks...
