The present invention relates to an integrated electric drive system comprising: a motor; a vehicle battery; the first conversion unit is used for converting alternating current from an external power grid or generated during regenerative feedback of a motor into direct current; a second conversion unit that performs a step-up or step-down operation on the direct current from the first conversion unit; an inverter which converts the direct current from the second conversion unit into alternating current; a first isolation transformer; a second isolation transformer; a first rectifier; a second rectifier; the switching conversion unit enables the first rectifier and the second rectifier to be connected in series or in parallel under the control of the control unit; and the control unit is used for selectively controlling the connection state of the switch conversion unit so as to realize different working modes of the system. The invention also relates to a vehicle comprising the system.
本发明涉及一种集成式电驱动系统,其包括:电机;车辆电池;第一转换单元,其将来自外部电网或电机再生反馈时所产生的交流电转换为直流电;第二转换单元,其对来自第一转换单元的直流电执行升压或降压操作;逆变器,其将来自第二转换单元的直流电转换成交流电;第一隔离变压器;第二隔离变压器;第一整流器;第二整流器;开关变换单元,其在控制单元的控制下使第一整流器和第二整流器以串联或并联的方式彼此连接;以及控制单元,其选择性地控制开关变换单元的连接状态,以实现系统的不同工作模式。本发明还涉及一种包括该系统的车辆。
