    Hello everybody

    I'm designing a 3 phase IGBT inverter and I'm searching an adequate driver. The drive I would like to use is a transformer-coupled push-pull gate drive. I'd like to use this kind to protect the driver because I'm working with high voltages. In the end I would like to use this inverter to generate high voltages i.e. the voltages equal to the European grid. Any suggestions wich driver I should use for this application? If you need extra information you can always ask me, I don't have much experience with inverters so I hope you can help me.

    In the link below you can find the principle at figure 2:

    Thank you

    What "high voltages" are you working with? How high? Most standard mosfet/igbt gate driver ICs are internally isolated to around 600V, and many three phase drivers are good to 1200V.

    I'll be working with a phase voltage of 400V (sqrt(3)*230V) if that is an answer to your question? To secure my driver I'd like to use the gate driver transformers from coilcraft: SD250-3L.

    Most people today use one of the many IC out there to do it. Sorry I can't help you.
