Hi EDA,
I'm doing a 3 wave fully controlled rectifier with 3 tca785's, the issue comes becouse of the control voltage, it should be connected to the pin 11 of the 3 tca785's but, every tca785 has its own ground point for his supply voltage and the control voltage has his own ground point too. And my question is, how could i isolate the control voltage for each tca785 to have them whith the same control voltage but it refered to each tca785 ground?
Salutes and thanks.
