Document Type and Number:
WIPO Patent Application WO/2023/160567
Kind Code:
A1
Abstract:
The present application relates to a PV charging circuit capable of reversely outputting a direct-current voltage source. The PV charging circuit capable of reversely outputting the direct-current voltage source comprises: a photovoltaic module (10) and an electrical storage module (20), which are connected to each other, the photovoltaic module (10) comprising a photovoltaic panel (PV) and a first field effect transistor assembly (101), and the electrical storage module (20) comprising a second field effect transistor assembly (201) and a power accumulator. The first field effect transistor assembly (101) is connected to two ends of the photovoltaic panel (PV), a negative electrode of the photovoltaic panel (PV) being grounded. The first field effect transistor assembly (101) is connected to controller modules, and the both ends of the second field effect transistor assembly (201) are connected to the two ends of the power accumulator, the second field effect transistor assembly (201) being connected to the first field effect transistor assembly (101) and the controller modules, and the two ends of the first field effect transistor assembly (101) being respectively used as a positive electrode and a negative electrode of a direct current voltage source output by the PV charging circuit.
