Abstract:
A power converting apparatus and a photovoltaic module are discussed. The power converting apparatus includes a converter including a tapped inductor and a first switch, the converter converting a level of an input direct current (DC) voltage and outputting the level-converted DC voltage, and an inverter including a plurality of switches, the inverter converting the level-converted DC voltage into an alternating current (AC) voltage. The inverter operates separately in a first switching mode where the inverter performs a switching operation at a first frequency for a first period of the converted AC voltage and a second switching mode where the inverter performs a switching operation at a second frequency for a second period of the converted AC voltage, the second frequency being lower than the first frequency.
