Abstract

See full text

In an electric vehicle inverter apparatus 100, a vehicle control controller 15 detects a switch open signal output from a collision detector 16 when the collision detector 16 is caused by a collision between electric vehicles to operate. Then, an inverter main circuit connection switch 10 of a high-voltage battery unit 8 is put into an open state. Thus, the direct-current power supply from a high-voltage battery 12 to a DC bus portion is interrupted. In addition, electric charges charged into a main circuit capacitor 7 are discharged by a forced discharge circuit portion 22b.
