POWER CONVERTING APPARATUS, CONTROL DEVICE, AND METHOD FOR CONTROLLING POWER CONVERTING APPARATUS

摘要

A power converting apparatus (1) is provided. The power converting apparatus (1) includes a power converter (10) configured to output a voltage to a load (3), and a controller (20) configured to output a PWM signal which is generated in response to a voltage command to the power converter (10). The power converter (10) includes a plurality of switching elements driven based on the PWM signal. The controller (20) is configured to generate the PWM signal such that a first period during which a zero voltage is outputted and a second period during which a non-zero voltage is outputted are adjusted according to the voltage command. The controller (20) is allowed to output the PWM signal which is set such that one first period and one or more second periods exist within an updating cycle of the voltage command, to the power converter (10).
