Intelligent power supply system for photovoltaic air conditioner and power supply method

The invention discloses an intelligent power supply system for a photovoltaic air conditioner and a power supply method. The system comprises a control module, a two-way AC/DC converter module, an inversion module and a photovoltaic system, wherein the two-way AC/DC converter module, the inversion module and the photovoltaic system are connected with the control module respectively; the photovoltaic system is used for converting solar energy into direct current; the two-way AC/DC converter module and the inversion module are connected with the photovoltaic system respectively; and according to the working conditions of the photovoltaic system and an air conditioning unit, the control module enables power supply to the air condition through the inversion module after establishing the connection of the photovoltaic system or enables excessive electric energy feedback through the two-way AC/DC converter module, or enables power supply to the air condition through the two-way AC/DC converter module and the inversion module after establishing the connection of the power grid. The method is a power supply method utilizing the above power supply system when the photovoltaic system and the air conditioning unit are in different working conditions. The intelligent supply system has the advantages of being simple and compact in structure, low in cost, high in power supply efficiency and high in stability; and an intelligent power supply control function of the photovoltaic air conditioner can be achieved on the basis of one set of system.
