Classification: CPC H  Y | IPC H

Claim 1:
2. The apparatus of claim 1,
wherein when obtaining the voltage command vector, the controller does not use a switching vector in which a switching state of the first inverter is [100] and a switching state of the second inverter is [011], a switching vector in which the switching state of the first inverter is and the switching state of the second inverter is [001], a switching vector in which the switching state of the first inverter is [010] and the switching state of the second inverter is [101], a switching vector in which the switching state of the first inverter is [001] and the switching state of the second inverter is [100], and a switching vector in which the switching state of the first inverter is [001] and the switching state of the second inverter is [110], and
wherein first, second, third digits of numbers indicating the switching states indicate the switching states of the switching elements in phases a, b, and c, respectively, in each of the first inverter and the second inverter, and a number “1” indicates that an upper switching element of an associated phase is turned on and a lower switching element thereof is turned off, and a number “0” indicates that the upper switching element of the associated phase is turned off and the lower switching element thereof is turned on.
