The embodiment of the invention provides a charging circuit, vehicle-mounted charging equipment and a vehicle. The charging circuit comprises a primary side conversion circuit, a secondary side first conversion circuit, a secondary side second conversion circuit and a transformer module, the first end of the transformer module is provided with a first winding, and the second end of the transformer module is provided with a second winding and a third winding; the first winding is connected with the primary side conversion circuit, the second winding is connected with the secondary side first conversion circuit, and the third winding is connected with the secondary side second conversion circuit; the secondary side second conversion circuit comprises a rectification module and is configured to independently adjust the output voltage based on the rectification module. The mutual influence of the voltage output by the secondary side second conversion circuit and the voltage output by the secondary side first conversion circuit can be avoided.
本申请实施例提供一种充电电路、车载充电设备及车辆,该充电电路包括原边转换电路,副边第一转换电路、副边第二转换电路以及变压器模块;变压器模块的第一端具有第一绕组,变压器模块的第二端具有第二绕组和第三绕组;第一绕组与原边转换电路连接,第二绕组与副边第一转换电路连接,第三绕组与副边第二转换电路连接;副边第二转换电路包括整流模块,副边第二转换电路配置为基于整流模块进行独立调节输出电压。可以避免副边第二转换电路输出的电压与副边第一转换电路输出的电压相互影响。
