The invention provides an electric vehicle inverter for controlling and driving multiple motors, which is applied to hub motors or wheel side motors for new energy automobile control, and comprises a central processing unit and more than two paths of driving circuits connected with the central processing unit, each path of driving circuit can be connected with a group of hub motors or wheel side motors, and the inverter is connected with more than two groups of hub motors or wheel side motors through more than two paths of driving circuits. According to the electric vehicle inverter for controlling and driving the multiple motors, the central processing unit and the two or more drive circuits connected with the central processing unit are arranged, one set of central processing unit can control two or more sets of motors at the same time, and compared with a plurality of sets of inverters for controlling and driving multiple sets of hub motors or wheel edge motors respectively, the number of the motors is reduced; the synchronous control performance is better, the inverter can receive control instructions of a plurality of motors at the same time, and the response speed and aging requirements of a motor control system are met.

    本发明提供了一种控制驱动多电机的电动车辆逆变器,应用于新能源汽车控制的轮毂电机或轮边电机,包括中央处理单元,以及与中央处理单元连接的两路以上驱动电路,每路驱动电路可连接一组轮毂电机或轮边电机,该逆变器通过两路以上的驱动电路连接两组以上的轮毂电机或轮边电机。本发明所述的一种控制驱动多电机的电动车辆逆变器通过设置中央处理单元,以及与中央处理单元连接的两路以上驱动电路,一组中央处理单元实现同时控制两组以上电机,相比于多组逆变器分别控制驱动多组轮毂电机或轮边电机,其同步控制性能更好,该逆变器可同时接收多个电机的控制指令,满足电机控制系统的响应速度和时效要求。
