  • Photovoltaic intelligent power supply
    Patent number: 10122176
    Abstract: A photovoltaic intelligent power supply, comprising a plurality of unit modules, and a communication unit (103) and a control unit (106), wherein all the unit modules are connected to the control unit (106) and the communication unit (103); each unit module comprises an input collection unit (101), a data acquisition unit (102), a boost unit (104), an arc isolation unit (105) and an anti-PID unit (107), wherein the input collection unit (101) is connected to a photovoltaic module; the data acquisition unit (102) is configured to acquire voltage and current state signals; the boost unit (104) is configured to perform interleaving chopping and operate in an MPPT mode; the arc isolation unit (105) is configured to receive instructions sent by the control unit (106) to execute opening and closing; and the anti-PID unit (107) is configured to receive instructions sent by the control unit (106) so as to generate proper DC voltages to be applied between a negative electrode of a cell panel and the ground.
