Abstract
A method of controlling a photovoltaic power system, can include: controlling a first current flowing through a connection line between an output terminal of a power conversion circuit and an input terminal of an inversion circuit according to a rapid shutdown signal; and controlling operation states of the power conversion circuit coupled to a photovoltaic panel in accordance with the first current, such that a voltage on the connection line meets preset requirements. A photovoltaic power system can include: an inversion circuit configured to be controlled to regulate a first current of an input line of the inversion circuit; and at least one power conversion circuit coupled in series with the input line, and being configured to transition among different operation states according to the first current.
