Title:
PHOTOVOLTAIC MODULE TURN-OFF CIRCUIT AND PHOTOVOLTAIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/116389
Kind Code:
A1
Abstract:
A photovoltaic module turn-off circuit and a photovoltaic device, comprising a first on-off switching tube, a voltage module, a first driving module, and a control chip. The voltage module is configured to obtain a power supply voltage of a chip according to an output voltage of a controlled photovoltaic module; the control chip is configured to send a circuit breaker control voltage signal to be processed to the first driving module; the first driving module is configured to obtain a circuit breaker control voltage signal; and the first on-off switching tube is connected to the controlled photovoltaic module in series and is configured to determine, according to the circuit breaker control voltage signal, on-off of an output end of the controlled photovoltaic module and an external circuit. According to the present invention, the output voltage of the controlled photovoltaic module is regulated and controlled, so that the turn-off circuit of the photovoltaic device having multiple components connected in series is prevented from matching, by means of a high-voltage chip, the high voltage after multiple components are connected in series, the difficulty and risk of chip design and production are reduced, and the production cost of the chip is reduced.
