  • Power control method and power control apparatus
    Patent number: 11394334
    Abstract: A power control method for calculating a duty command value to be used for a PWM control, generating a PWM signal corresponding to a comparison result between the duty command value and a carrier signal, and applying a PWM voltage to a load by driving an inverter based on the PWM signal. The power control method comprises obtaining a compensation amount according to a phase shift generated in the PWM voltage so as to compensate for the shift, correcting the compensation amount according to a cycle of the carrier signal, and correcting the duty command value depending on whether a strength of the carrier signal is increasing or decreasing using the corrected compensation amount.
