After powering this coil at 800VDC for extended periods of time, I experienced an IGBT failure (note that this was the first failure in over a year). The IGBT that failed also had its TVS string come disconnected (though the TVS's were not damaged). So I began to investigate what was going on here, and found a significant oversight in my original design. The problem, as expected, had to do with voltage transients. I turns out that the inductance between my large electrolytic capacitors, and the bridge, along with the decoupling film caps located on the bridge, had a resonant frequency of around 40khz! My rail voltage was ringing up to 160% of the input voltage, so at 800VDC input, this would have presented 1280V across the 1200V IGBT devices... yikes! Here is a picture of the output from one of the half-bridges in this condition:
The only way to fix this condition is to minimize the inductance between the IGBTs and the main filter capacitors. Simply putting small film caps on the IGBTs *does not cut it*! So I came up with this solution:
