Hi, new Forum member here! Decided it was FINALLY time I join and ask some questions seeing as I'm running up against a real quandary here.
So, context: I work for an electronics assembly materials company (develops solder paste, sinter materials, epoxies, etc) and I work on customer applications with the sinter material group. I have my BS in Mechanical Engineering from the University of Maryland for additional context.
One of my projects involves a novel double sided inverter module for a company (name disclosed) and I am getting some strange feedback from the customer group. The first pass I made at this project, the modules failed high voltage testing. Second round, the modules passed high voltage, however they failed in DC testing.
So, my questions are the following: What are standard tests for IGBT inverters (for electric vehicles, solar power inverters, etc)? Does high voltage test include switching of the gate for the IGBT or is it a characteristic curve generator?
