Abstract
In the event of collision of a vehicle, a control device for a power converting apparatus in the vehicle is supplied with a power source voltage for operations thereof, using electric power resulting from residual charges accumulated in smoothing capacitors provided in the power converting apparatus. With such a configuration, even if a power source voltage for the control device is not supplied from outside the power converting apparatus due to disconnection of a line, the residual charges accumulated in the smoothing capacitor provided in the power converting apparatus can be discharged.
Claims15
A power converting apparatus for a vehicle,
- the vehicle including
- a first power storage device for supplying direct-current power to the power converting apparatus,
- a relay configured to be capable of switching between supply and interruption of the direct-current power to the power converting apparatus, and
- a collision detecting unit for detecting collision of the vehicle,
- the power converting apparatus comprising:
- a capacitor;
- a power converting unit configured to include a switching element and convert the power supplied from said first power storage device via said relay;
- a control device for controlling said power converting unit by controlling said switching element, so as to consume a residual charge in said capacitor;
- and
- a power supply unit for supplying said control device with a power source voltage using power accumulated in said capacitor, when the collision of the vehicle is detected and said residual charge is consumed with said first power storage device being electrically separated from the power converting apparatus by said relay.
