Title:
PHOTOVOLTAIC MODULE
Document Type and Number:
WIPO Patent Application WO/2019/098709
Kind Code:
A1
Abstract:
A photovoltaic module can include a solar cell module including a plurality of solar cells; a converter configured to convert a level of DC power input from the solar cell module; a DC-terminal capacitor configured to store DC power output from the converter; an inverter including a plurality of switching elements and configured to convert DC power from the DC-terminal capacitor into AC power; and a controller configured to control the inverter, in which the converter controls some switching elements among of the plurality of switching elements included in the inverter to perform switching at a first switching frequency, and controls other switching elements among the plurality of switching elements included in the inverter to perform switching at a second switching frequency higher than the first switching frequency.
