Title:
INVERTER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/065882
Kind Code:
A1
Abstract:
According to the present invention, when a dynamo-electric machine (80) is in a state of rotation while a contactor (9) is in an open state, an inverter (10) is controlled so as to suitably stop the operation of the inverter (10). An inverter control device (20) controls an inverter (10) of a dynamo-electric-machine drive device (2) comprising: the inverter (10), which is connected to a DC power supply (11) via a contactor (9) and also is connected to an AC dynamo-electric machine (80); and a smoothing capacitor (4). When the dynamo-electric machine (80) is in a state of rotation while the contactor (9) is in an open state, the inverter control device (20) executes upper and lower active short circuit control for recirculating current between the dynamo-electric machine (80) and the inverter (10) while an upper switching element (31) and a lower switching element (32) of at least one phase, from among switching elements (3) of a plurality of phases of the inverter (10), are in an on state.
