Title:
INTEGRATED INVERTER-CHARGER DEVICE AND CONTROL METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2021/020638
Kind Code:
A1
Abstract:
The present invention relates to an integrated inverter-charger device. According to one aspect of the present invention, an integrated inverter-charger device may be provided which comprises: a charging unit of which one end is connected to a power input unit for supplying alternating current power, and the other end is provided to a transformer which is isolated into a primary side and a secondary side; a conversion unit which, in a charging mode, converts the alternating current power provided from the charging unit into direct current power for charging a battery, and in an operation mode, converts direct current power provided from the battery into power for driving a three-phase electric motor; a transfer switch unit which comprises at least one transfer switch which is switched so that the conversion unit selectively forms a closed circuit with one between the secondary side of the transformer and the three-phase electric motor; and a control unit which controls the switching of the transfer switch so that in the charging mode, the secondary side of the transformer and the conversion unit form a closed circuit, and in the operation mode, the three-phase electric motor and the conversion unit form a closed circuit.
