Title:
電力変換装置およびヒートポンプ装置
Document Type and Number:
Japanese Patent JP6450016
Kind Code:
B2
Abstract:
A power converting apparatus includes: an inverter converting a direct-current voltage supplied from a power supply unit into an alternating-current voltage and outputting the alternating-current voltage to a motor; and an inverter control unit outputting synchronous PWM (Pulse Width Modulation) signals for driving switching elements of the inverter. A frequency of the synchronous PWM signals is periodically varied when periodic pulsation occurs in a load connected to the motor.
