METHOD AND APPARATUS FOR CONTROLLING SERIES-PARALLEL SWITCHING CIRCUIT, AND CONTROLLER AND STORAGE MEDIUM

WIPO Patent Application WO/2023/050656

A1

The present application relates to the technical field of power electronics. Provided are a method and apparatus for controlling a series-parallel switching circuit, and a controller and a storage medium. The method comprises: acquiring a pre-generated circuit control timing diagram, wherein the circuit control timing diagram is configured to indicate the state of a state switching unit at at least one moment, and change states of output currents and output voltages of at least two direct-current output units at the at least one moment; and according to the circuit control timing diagram, controlling the state of the state switching unit and the output currents and the output voltages of the at least two direct-current output units, and controlling the state of a discharging unit, so as to switch the at least two direct-current output units from a parallel state to a series state, or from the series state to the parallel state. By means of the present solution, online series-parallel switching can be realized without shutdown, such that the problem in the related art of it being impossible to perform normal charging due to interruption of output power during series-parallel switching is solved, thereby meeting the normal charging requirements of different loads.
