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 switching sequence corresponding to the switching mode. Therefore, by adjusting the input voltage or the wave sending quantity of the power conversion module during series-parallel switching, the power loss can be minimized during series-parallel switching of the output series-parallel circuit of the converter.
本申请公开了一种功率变换模块的串并联切换方法、装置、设备及介质,应用于电力电子技术领域,用以解决现有技术中功率变换模块切换导致的功率损失问题。具体为:在满足切换条件的情况下,确定切换模式;若切换模式为串联切换为并联,则确定切换模式对应的调节参数为功率变换模块的输入电压;若切换模式为并联切换为串联,则确定切换模式对应的调节参数为功率变换模块的发波量;针对切换模式对应的调节参数进行调节,控制开关模块按照与切换模式对应的切换顺序进行切换。这样,通过在串并联切换时调节功率变换模块的输入电压或发波量,可以实现变换器输出串并联电路在串并联切换时,功率损失最小化。
