I managed to break two, yes 2 of my testing setup Volt inverter power stages! It was a stupid wiring mistake and now i keep getting faults at high voltage start.
Does anyone have a low price Chevy Volt inverter with both power stages still in working order? I need one for paralell operation testing.
I dont care if the coolant pipes or connectors are damaged, i have spares here...
.
tnx

I have one here with a broken cooling fitting. Just pay shipping.

OK that is strange... i found another inverter that is exhibiting the same Fault output behaviour that is plaging mine. A friend asked me for my opinion.
When i connect my PCB board to Volt inverter and i apply HV i get intermittent fault signal. reset LED is blinking very fast and so inverter drops in and out of the Fault condition.
I tried to reduce signal resistor and increase pullup resistor, but the signal derives from fault transistor on the driver board. Anyone seen anything similar? Usually when IGBT is damaged i only get floating pin. Maybe only signal transistor is damaged?
I will investigate this further with my scope.
