CPC H02P 27/085 (2013.01) [H02P 21/22 (2016.02)] | 12 Claims |
1. A motor driving device that drives a motor having a plurality of windings corresponding to a plurality of phases, the motor driving device comprising:
a first inverter configured to include a plurality of first switching elements and connected to first stages of the plurality of windings;
a second inverter configured to include a plurality of second switching elements and connected to second stages of the plurality of windings; and
a controller configured to fix switching states of the second switching elements which has larger switching loss than the first switching elements and switch the first switching elements to compose target voltage vectors when the motor is driven in an open end winding type by operating the first inverter and the second inverter in a space vector pulse width modulation mode.
