Series-parallel connection switching method and device of power conversion module, equipment and medium

The invention discloses a series-parallel connection switching method and device for power conversion modules, equipment and a medium, is applied to the technical field of power electronics, and is used for solving the problem of power loss caused by switching of the power conversion modules in the prior art. The method specifically comprises the steps of determining a switching mode under the condition that a switching condition is met; if the switching mode is switched from series connection to parallel connection, determining an adjustment parameter corresponding to the switching mode as the input voltage of the power conversion module; if the switching mode is switched from parallel connection to series connection, determining that an adjusting parameter corresponding to the switching mode is the wave emission quantity of the power conversion module; and adjusting according to the adjusting parameters corresponding to the switching mode, and controlling the switch module to switch according to the switchi
