Hi Jack,
I'm asking you because you seem to have success with igbts, but anyone with knowledge please feel free to elaborate.
I found some high power igbts, not cheap but I think I can afford them, anyways it's got me rethinking my design. They claim to have internal freewheel diodes, does this mean that these can be installed without external freewheel diodes? If so, will the control board that Paul has drive them without issue?
If not, please explain why.
