Abstract
A resonance suppression control block includes a high-pass filter for extracting an AC component of DC link voltage, and a gain section for outputting a correction signal obtained by multiplying the AC component by a gain. A control unit controls an inverter based on a signal obtained by adding the correction signal to the voltage instruction. Thus, a power conversion apparatus with a simple configuration can be obtained that can suppress resonance of a DC link section and omit extra work for performing adjustment again in accordance with a power supply frequency.
