Title:
PHOTOVOLTAIC ASSEMBLY, PHOTOVOLTAIC POWER GENERATION SYSTEM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/279754
Kind Code:
A1
Abstract:
Provided are a photovoltaic assembly (1), a photovoltaic power generation system, and an electronic device. The photovoltaic assembly (1) comprises: a third junction box (13) provided with a first input bypass diode (D1), a second junction box (12) provided with a second input bypass diode (D2), and a first junction box (11) provided with an auxiliary power supply module (111), a control module (112), a transistor switch (Q), an output bypass module (113) and a signal conversion module (114). Two input ends of the auxiliary power supply module (111) are respectively connected to two ends of a third photovoltaic unit (16), an output end of the auxiliary power supply module (111) is connected to the control module (112), a first electrode and a second electrode of the transistor switch (Q) are respectively connected to a second end of the third photovoltaic unit (16) and a first end of a first side of the signal conversion module (114), and a second side of the signal conversion module (114) is connected to the control module (112). The output bypass module (113) is connected between a second end of a first photovoltaic unit (14) and the second electrode of the transistor switch (Q). An external junction box is not required, and the photovoltaic assembly (1) is turned off in a low-cost and low-voltage manner.
