ABSTRACT:
An inverter system for a vehicle including a housing, a primary stage, a secondary stage and a fault detection circuit is provided. The primary stage is configured to receive a first voltage signal from an energy power source to generate a second voltage signal. The secondary stage is configured to generate a third voltage signal in response to the second voltage signal. At least one of the primary and the secondary stages define at least one resistance point for discharging leakage current responsive to generating the third voltage signal. The fault detection circuit is configured to electrically couple the primary stage and the secondary stage to provide the second voltage signal to the secondary stage and to measure a portion of the third voltage signal to determine whether the leakage current being discharged through the at least one resistance point is within a predetermined current range.
