POWER CONVERTING APPARATUS, AND PHOTOVOLTAIC MODULE

摘要

The present invention relates to a power conversion device and a sunlight module. The power conversion device according to the embodiment of the present invention comprises a switching unit which has a switching element and switches the inputted direct current power to be selectively outputted; a converter which has a tab inductor and a switching element and level converts the direct current power from the switching unit to be outputted; and an inverter which has a plurality of switching elements and converts the level converted direct current power to an alternating current power, wherein the converter operates in a first power conversion mode during the turn-off section of the switching element in the switching unit while operating in a second power conversion mode during the turn-on section of the switching element in the switching unit, thereby improving the output current quality.
