PHOTOVOLTAIC INVERTER AND AIR CONDITIONER

摘要

Provided is a photovoltaic inverter, comprising a basic photovoltaic inverter unit. The basic photovoltaic inverter unit comprises a photovoltaic battery assembly, a DC-DC voltage booster, a first switching switch, a grid-connected inverter, and a grid-connected filter; the photovoltaic battery assembly, the DC-DC voltage booster, the grid-connected inverter, the grid-connected filter, and an alternating current grid are electrically connected in sequence; the first switching switch comprises one first input terminal and two output terminals; the two output terminals are the first output terminal and the second output terminal; the input terminal of the first switching switch is connected to the output terminal of the DC-DC voltage booster; the first output terminal of the first switching switch is connected to the input terminal of the grid-connected inverter for outputting the alternating current into the grid; the second output of the first switching switch serves as a direct current bus terminal for outputting the direct current. The present invention also relates to an air conditioner. The photovoltaic inverter and the air conditioner of the present invention enhance the utilization rate of the electricity generated by the photovoltaic battery assembly.
