Abstract
A motor driving device drives a motor having a plurality of windings corresponding to a plurality of phases. The motor driving device includes: 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 and switch the first switching elements to compose target voltage vectors if 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.
