The invention relates to the technical field of power electronics, in particular to a charging module control method, a charging module and a charging pile, the charging module comprises a plurality of power converters with input connected in series and output connected in parallel, and the method comprises the following steps: obtaining target charging data needing to be output by the charging module and actual charging data actually output at present; obtaining an upwarp coefficient for upwarp control according to the target charging data and the actual charging data; and performing upwarp control on the plurality of power converters based on the upwarp coefficients. Therefore, upwarp control is carried out on the power converter according to the target charging data and the actual charging data of the charging module, meanwhile, direct-current bus voltage sharing can be achieved, voltage sharing control is facilitated, and fault shutdown of the charging module can be reduced or avoided.

    本发明涉及电力电子技术领域,具体提供一种充电模块控制方法、充电模块和充电桩,充电模块包括输入串联且输出并联的多个功率变换器,方法包括以下步骤:获取充电模块需要输出的目标充电数据和当前实际输出的实际充电数据;根据目标充电数据和实际充电数据得到用于上翘控制的上翘系数;基于上翘系数分别对多个功率变换器进行上翘控制。由此,根据充电模块的目标充电数据和实际充电数据对功率变换器进行上翘控制,同时可实现直流母线均压,便于均压控制,可减少或者避免充电模块故障关机。
