The invention belongs to the technical field of electronic circuits, and particularly relates to a vehicle-mounted charging device, a vehicle-mounted charging system and a vehicle. The first driving control module and the second driving control module control the first low-side switching tube and the second low-side switching tube to be switched on alternately, so that the first bootstrap driving module and the first low-side switching tube as well as the second bootstrap driving module and the second low-side switching tube alternately form a loop, charges are released, the problem of virtual voltage is solved, and the service life of the device is prolonged. In addition, the method does not need to add any auxiliary circuit, can be realized by fully utilizing a hardware circuit, and has the advantages of high reliability and low cost.

    本发明属于电子电路技术领域,尤其涉及一种车载充电装置、车载充电系统以及车辆,在第一驱动控制模块和第二驱动控制模块控制第一高侧开关管关断和第二高侧开关管关断时,第一驱动控制模块和第二驱动控制模块控制第一低侧开关管和第二低侧开关管交替导通,以使第一自举驱动模块和第一低侧开关管、第二自举驱动模块和第二低侧开关管交替形成回路,从而释放电荷,以解决“虚电压”的问题,避免发生主动放电装置频繁启动的情况,且该方式不需要增加任何辅助电路,充分利用硬件电路即可实现,具有高可靠、低成本的优势。
