Hi. I am designer of AC Motor speed controllers. I use IGBT as a switching device for PWM algorithms. I have designed IGBT Gate Driver Circuit and DC-DC Converter. The transformer insulation voltage is 5000V(rms) between primary to secondaries and secondary to secondary and I have used Avago’s ”HCPL-316J” gate drive opto-coupler for IGBT Gate Driver Circuit . IGBT parameters are 1200V/150A and working voltage is 380-480VAC(rms).

Now, I have a special project. IGBT parameters are 1700V/150A and working voltage is 500-600 VAC(rms). I will design a new IGBT Gate Driver Circuit. I have searched some about the IGBT Gate Drive cores. Concept’s “2SC0108T2A0-17” driver core can drive all usual IGBT modules up to 600A/1200V and 450A/1700V. But this is a high-cost solution.
I am searching if I can find a low-cost solution. Can I use Avago’s ”HCPL-316J” gate drive opto-coupler for IGBT Gate Driver Circuit for IGBT parameters are 1700V/150A and working voltage is 500-600VAC(rms) or another gate drive opto-coupler?
