POWER CONVERTING APPARATUS, CONTROL DEVICE OF POWER CONVERTING APPARATUS, AND CONTROL METHOD OF POWER CONVERTING APPARATUS

摘要

A power converting apparatus includes: a power converter provided between each phase of an AC power source and each phase of a load; a controller for controlling the power converter to perform a power conversion control between the AC power source and the load; and a filter provided between the AC power source and the power converter. The controller has: an oscillation component detector to detect an oscillation component of an input voltage of the power converter or an oscillation component included in a current flowing through the filter; and an output voltage controller to control an output voltage of the power converter to suppress a resonance of the filter based on the oscillation component.
