The invention relates to an integrated electric drive system and a vehicle. The system comprises a motor; a energy storage unit; a first conversion unit which is configured to convert alternating current generated during regeneration feedback of an external power supply or the motor of the vehicle into direct current or convert the direct current from the energy storage unit into alternating current; a second conversion unit which configured to perform a step-up or step-down operation on the direct current from the first conversion unit or the energy storage unit; a third conversion unit whichconfigured to perform a conversion operation on the direct current from the second conversion unit or the energy storage unit, the third conversion unit including an inverter, an isolation transformer, a first rectifier, and a second rectifier; and a control unit which is configured to selectively control all the modules so as to realize different working modes of the system. The invention further relates to an electric vehicle including the system. According to the system and the vehicle, multiplexing of the power electronic device is realized; and the manufacturing cost of the vehicle is reduced.

    本公开涉及一种集成式电驱动系统及车辆,包括:电机;能量存储单元;第一转换单元,其配置为将来自车辆外部电源或电机再生反馈时所产生的交流电转换为直流电,或者将来自能量存储单元的直流电转换为交流电;第二转换单元,其配置为对来自第一转换单元或能量存储单元的直流电执行升压或降压操作;第三转换单元,其配置为将来自第二转换单元或能量存储单元的直流电执行转换操作,第三转换单元包括逆变器、隔离变压器、第一整流器和第二整流器;以及控制单元,其配置为选择性地控制上述各个模块,以实现系统的不同工作模式。本公开还涉及一种包括该系统的电动车辆。根据本公开的系统与车辆实现了功率电子器件的复用;降低了车辆的制造成本。
