  • Patent number: 10177662
    Abstract: A first control device sends a common required carrier frequency, and a synchronizing signal that is synchronous with a first triangular wave, to a second control device. On satisfaction of a first condition that a carrier frequency of the first triangular wave is different from the required carrier frequency, the first control device changes the carrier frequency of the first triangular wave to value of the required carrier frequency. The second control device calculates a recognizing carrier frequency of the first triangular wave, based on the synchronizing signal. On satisfaction of second conditions that a carrier frequency of a second triangular wave is different from the recognizing carrier frequency and that the recognizing carrier frequency is equal to the required carrier frequency from the first control device, the second control device changes the carrier frequency of the second triangular wave to value of the required carrier frequency.
