Claim 1:
2. The rotating electrical machine control device according to claim 1, wherein
in the pulse width modulation control, a plurality of pulses are generated based on an instruction value and a carrier,
in the mixed pulse width modulation control, a plurality of pulses are generated based on a half carrier and the instruction value, the half carrier being the carrier whose wave height is half of a variable range of the instruction value, and
in the mixed pulse width modulation control, a plurality of pulses are generated using:
a double half carrier and single reference scheme in which pulses for the first inverter are generated based on a first half carrier and the instruction value common to the first inverter and the second inverter, and pulses for the second inverter are generated based on a second half carrier and the instruction value, the first half carrier being set, as the half carrier, on one of a higher voltage side and a lower voltage side than a center of an amplitude of the instruction value, and the second half carrier having a same phase as the first half carrier and being set on an other one of the higher voltage side and the lower voltage side than the center of the amplitude of the instruction value; or
a double half carrier and double reference scheme in which pulses for the first inverter are generated based on a first half carrier and a first instruction value for the first inverter, and pulses for the second inverter are generated based on a second half carrier and a second instruction value for the second inverter, the first half carrier being set, as the half carrier, on one of the higher voltage side and the lower voltage side than the center of the amplitude of the instruction value, the second half carrier differing from the first half carrier in phase by 180 degrees and being set on a same side as the first half carrier, and the second instruction value differing from the first instruction value in phase by 180 degrees.
