Power conversion system
A surge according to a change of a switching state can be reduced without increasing a torque ripple of a motor. A first switching signal to control switching of a boost converter is generated on the basis of a comparison of a first duty command value and a first triangular wave carrier of the boost converter. A second switching signal to control switching of an inverter is generated on the basis of a comparison of a second duty command value and a second triangular wave carrier of the inverter. In addition, the second triangular wave carrier is generated such that a frequency of the second triangular wave carrier becomes equal to a frequency of the first triangular wave carrier and a phase of the second triangular wave carrier is different from a phase of the first triangular wave carrier by 180 degrees.
