POWER SOURCE QUALITY MANAGEMENT SYSTEM AND AIR-CONDITIONING DEVICE

摘要

According to the present invention, power is supplied to a power conversion device (3) from an alternating-current power source (1). An active filter device (2) that is a power source quality improvement part improves the quality of the alternating-current power source (1). A controller (37) regulates the operation of the power conversion device (3) such that a power source power, a power source current, and a power source harmonic when a malfunction detection part (4) has detected that the active filter device (2) is malfunctioning are at or below maximum values for the power source power, the power source current, and the power source harmonic when the active filter device (2) is not malfunctioning.
