Abstract
A rapid shutdown device and a photovoltaic device are provided. The rapid shutdown device according to the present disclosure includes a first on-off switching transistor, a voltage module, a first driving module and a control chip. The voltage module adapts voltage outputted by a controlled photovoltaic module to the control chip. Therefore, the rapid shutdown device for a photovoltaic device formed by multiple photovoltaic modules connected in series unnecessitated a high-voltage chip. Instead, a common low-voltage chip is suitable for such photovoltaic device. Further, since an output voltage signal of the low-voltage chip is insufficient to directly drive the first on-off switching transistor connected to the controlled photovoltaic module in series, the first driving module is added to adapt the electric signal sent by the control chip to the first on-off switching transistor.
