Title:
MAIN CONVERSION DEVICE FOR ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/136220
Kind Code:
A1
Abstract:
A main conversion device (100) is provided with a first power conversion unit (111), a second power conversion unit (112), an auxiliary power supply device (113), and an operation control unit (120). The first power conversion unit (111) is connected to a circuit electrically connected to an aerial line (105), and an intermediate link unit (121), and converts power therebetween. The second power conversion unit (112) is connected to the intermediate link unit (121) and a circuit electrically connected to an induction motor (103), and converts power therebetween. The auxiliary power supply device (113) receives power from the intermediate link unit (121) and supplies the power to a load (104). On the basis of a value indicating the acceleration state of a vehicle, a value corresponding to a vehicle speed, auxiliary power supply power, and the limit value of power to be regenerated to the aerial line (105), the operation control unit (120) controls the operation and stop of the first power conversion unit (111) such that the power to be supplied to the auxiliary power supply device (113) is more than or equal to the auxiliary power supply power and the power to be regenerated to the aerial line (105) is less than or equal to the limit value.
