Dear Friends,
I want to use MOSFET/IGBT as switch at 600V DC. In our current circuit, controlled AC(using TRIAC) is switched using RELAY and then it is rectified to get DC. but now we are having SMPS with DC output, which we want to switch. But as RELAY may give problem to HV DC in long term and also i dont think anybody supplies RELAY for HVDC.
So please suggest me the circuit, voltage at gate available is 8V now. But if any component needs higher, I can use more.
Also tell me if I can use HV SCR.........
Please help me.
Awaiting your expert comments !!!
