Abstract
Discussed is a photovoltaic module including: a solar cell module including a plurality of solar cells; a converter to convert a level of first direct current (DC) power input from the solar cell module, and to output second DC power; an inverter to convert the second DC power supplied from the converter into alternating current (AC) power; and a controller to control the converter and the inverter, wherein the converter comprises: a full-bridge switching part to switch the first DC power; a transformer having an input side connected to an output terminal of the full-bridge switching part; and a half-bridge switching part connected to an output side of the transformer, wherein the controller changes a switching frequency of the full-bridge switching part and the half-bridge switching part in a first section of a waveform.
