The invention relates to the field of vehicle-mounted chargers, in particular to a control circuit compatible with multiple platforms, a vehicle-mounted charger and a control system, and the control circuit comprises a transformer T1 which is provided with a primary winding W1, a first secondary winding W21 and a second secondary winding W22; the primary side circuit is coupled with the primary side winding W1; the input end of the high-voltage secondary side circuit is coupled with the first secondary side winding W21 and the second secondary side winding W22; a switching unit; for a high-voltage secondary side circuit, the switching unit is arranged among the first secondary side winding W21, the second secondary side winding W22 and the high-voltage secondary side circuit and is used for switching the series-parallel connection relation of the first secondary side winding W21 and the second secondary side winding W22; for a plurality of high-voltage secondary circuits, the switching unit is arranged between the output ends of the high-voltage secondary circuits and is used for switching the series-parallel connection relation of the output ends. The vehicle-mounted charger has the effect of widening the output range of the vehicle-mounted charger, so that the same vehicle-mounted charger can meet the charging requirements of different vehicle-mounted batteries.

    本申请涉及车载充电机领域,尤其涉及一种兼容多平台的控制电路、车载充电机及控制系统,控制电路包括:变压器T1,设置有原边绕组W1,第一副边绕组W21、第二副边绕组W22;原边电路,与原边绕组W1耦合;一个或多个高压副边电路,输入端与第一副边绕组W21、第二副边绕组W22耦合;切换单元;对于一个高压副边电路,切换单元设置在第一副边绕组W21、第二副边绕组W22与高压副边电路之间,用于切换第一副边绕组W21与第二副边绕组W22的串并联关系;对于多个高压副边电路,切换单元设置高压副边电路的输出端之间,用于切换输出端的串并联关系。本申请具有拓宽车载充电机输出范围的效果,使同一台车载充电机能满足不同车载电池的充电需求。
