Abstract
In an electric vehicle inverter apparatus, a vehicle control controllerdetects a switch open signal output from a collision detectorwhen the collision detectoris caused by a collision between electric vehicles to operate. Then, an inverter main circuit connection switchof a high-voltage battery unitis put into an open state. Thus, the direct-current power supply from a high-voltage batteryto a DC bus portion is interrupted. In addition, electric charges charged into a main circuit capacitorare discharged by a forced discharge circuit portion
