Abstract
A photovoltaic rapid shutdown device and a photovoltaic system are provided. The device includes a first switch, a second switch, a bypass diode, an auxiliary power supply, a control circuit and a communication circuit. One of multiple photovoltaic modules serves as a power supplying photovoltaic module, and an output terminal of the power supplying photovoltaic module is connected to an input terminal of the auxiliary power supply. The first switch is connected in series between the power supplying photovoltaic module and an adjacent photovoltaic module. Two terminals of the second switch are connected to positive and negative output terminals of a branch formed by the multiple photovoltaic modules connected in series, respectively. A cathode of the bypass diode is connected to a low voltage terminal of the adjacent photovoltaic module.
