Abstract
A series-parallel switching method and apparatus, a power conversion circuit, and an electronic device are provided. The power conversion circuit includes a control unit and two power conversion modules. The two power conversion modules are connected in series or connected in parallel. Either of the power conversion modules includes output terminals and first switch branches, where the first switch branches are connected to the output terminals, and the output terminals are configured to connect to a load. The first switch branches are connected to the control unit, and the first switch branches are configured to switch an operating state according to a control signal output by the control unit, to provide an energy discharge loop when the two power conversion modules are switched from a parallel connection to a series connection, where the operating state includes a stopping state and a running state.
