摘要
The present disclosure relates to frequency control of power conversion modules for decreasing THD (Total Harmonic Distortion) in a power conversion device in which a plurality of power conversion modules operate in parallel. In one aspect of the present disclosure, an embodiment provides a power conversion device comprising a plurality of power conversion modules being connected in parallel to receive input power and provide output AC power, and a frequency controller controlling each operating frequency of the plurality of power conversion modules, wherein, the frequency controller may include a function as a first frequency regulating step for regulating each operating frequency of the plurality of power conversion modules, so that the operating frequencies of the plurality of power conversion modules have a specific relationship with each other.
