Abstract

See full text

A power conversion device includes a main battery, an auxiliary battery, an inverter circuit, a high-voltage wiring, a smoothing capacitor, a main wiring, a subsidiary wiring, a DC-DC converter and a controller. The DC-DC converter is connected to a high-potential wire of the main wiring, a low-potential wire of the main wiring, a high-potential wire of the subsidiary wiring, a low-potential wire of the subsidiary wiring, the high-potential wire of the high-voltage wiring and the low-potential wire of the high-voltage wiring. The controller is connected to the auxiliary battery and the DC-DC converter. The DC-DC converter is configured to supply a power stored in the smoothing capacitor to the controller through the DC-DC converter such that the controller drives the inverter circuit and that the power stored in the smoothing capacitor is supplied to the motor through the inverter circuit, when a collision of the vehicle is detected.
