Document Type and Number:
Japanese Patent JP2015133903
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power conversion apparatus and a photovoltaic module including the same.SOLUTION: The power conversion apparatus includes: a converter unit to convert DC power supply from a solar cell module, the converter unit including a plurality of interleaving converters; and a controller to control the converter unit. The controller changes switching periods of the plurality of interleaving converters and changes phase differences between the plurality of interleaving converters during operation sections, in response to a change of the switching periods. Consequently, it is possible to prevent instantaneous reduction of output power due to change of switching frequencies.
