The invention provides a vehicle-mounted high-voltage system which comprises a vehicle-mounted charger and a vehicle-mounted DC/DC, and further comprises a filtering integrated device connected between the high-voltage side of the vehicle-mounted charger and the high-voltage side of the vehicle-mounted DC/DC, and the filtering integrated device is integrated with a first filter and a second filter which are used for filtering the high-voltage side of the vehicle-mounted charger and filtering the high-voltage side of the vehicle-mounted DC/DC, and the current ripples at the high-voltage side of the vehicle-mounted charger and the high-voltage side of the vehicle-mounted DC/DC are absorbed. Compared with the prior art, the utilization rate of the filter device is improved, the occupied volume of the filter device is reduced, and the layout setting is optimized.

    本发明提出了一种车载高压系统,其包括车载充电机、车载DC/DC,还包括连接于车载充电机的高压侧和车载DC/DC的高压侧之间的滤波集成装置,所述滤波集成装置集成有对车载充电机高压侧滤波和对车载DC/DC高压侧滤波的第一滤波器和第二滤波器,并用于吸收所述车载充电机高压侧和车载DC/DC高压侧的电流波纹。与现有技术相比,本发明提高了滤波器件的利用率,减小了滤波器件占用的体积,优化了布局设置。
