POWER CONVERSION APPARATUS AND AIR CONDITIONER INCLUDING THE SAME

摘要

Disclosed herein are a power conversion apparatus and an air conditioner including the same. The power conversion apparatus includes a converter including a switching element and configured to convert an input alternating current (AC) voltage into a direct current (DC) voltage and to output the DC voltage, and a controller configured to control the converter. The controller divides a half-period of the input AC voltage into a plurality of periods according to a level or phase of the input AC voltage and changes a switching frequency of the switching element in at least some of the plurality of periods. Accordingly, it is possible to increase converter efficiency.
