The invention provides a power system, an electric drive system and a vehicle. The power system comprises a radiator which is provided with a concave space and is filled with cooling liquid; the plurality of power devices are located in the concave space, and the plurality of power devices are connected with the inner wall of the radiator; the at least two bus capacitors are located on the two sides of the radiator, and the at least two bus capacitors are connected with the two sides of the radiator; and the PCB is electrically connected with the plurality of power devices and the at least two bus capacitors. According to the power system, the radiator is arranged to be connected with the power devices and the bus capacitors at the same time, the radiator can conduct heat dissipation on the power devices and the bus capacitors at the same time, the PCB is electrically connected with the multiple power devices and the at least two bus capacitors to form the power system, and therefore the heat dissipation performance of the power system is good.

    本发明提供了一种功率系统、电驱系统及车辆。功率系统包括:散热器,散热器具有凹部空间,散热器内通有冷却液;多个功率器件,多个功率器件位于凹部空间内,多个功率器件与散热器的内壁连接;至少两个母线电容,至少两个母线电容位于散热器的两侧,至少两个母线电容与散热器的两侧连接;PCB电路板,PCB电路板与多个功率器件、至少两个母线电容电性连接。通过设置散热器与功率器件、母线电容同时连接,使得散热器不仅能够对功率器件进行散热,同时也能够对母线电容进行散热,PCB电路板与多个功率器件、至少两个母线电容电性连接,形成功率系统,从而使得该功率系统的散热性能良好。
