The invention discloses a motor controller and an electric vehicle with the same, and the motor controller comprises a shell, an IGBT power module, a direct current filtering module, an alternating current busbar and a direct current bus capacitor, and the IGBT power module is arranged in the shell; the direct current filtering module is arranged in the shell, is positioned at one end of the IGBT power module and is electrically connected with the IGBT power module; the alternating current busbar is arranged in the shell, is positioned at the other end of the IGBT power module and is electrically connected with the IGBT power module; and the direct current bus capacitor is arranged below the shell, is electrically connected with the IGBT power module, and is overlapped with the IGBT power module. Therefore, the arrangement positions of the shell, the IGBT power module, the direct-current filtering module, the alternating current busbar and the direct current bus capacitor are more reasonable, and the space occupation of the motor controller can be reduced, so that the arrangement and installation of the motor controller on a power assembly are more convenient; and the compact design of the motor controller is realized, and the use requirement of high power density is met.

    本发明公开了一种电机控制器以及具有其的电动车辆,电机控制器,包括:壳体、IGBT功率模块、直流滤波模块以及交流母排、直流母线电容,IGBT功率模块设置在壳体内;直流滤波模块设置在壳体内,且位于IGBT功率模块的一端,并与IGBT功率模块电连接;交流母排设置在壳体内,且位于IGBT功率模块的另一端,并与IGBT功率模块电连接;直流母线电容设置在壳体的下方,与IGBT功率模块电连接,并与IGBT功率模块叠置。由此,壳体、IGBT功率模块、直流滤波模块以及交流母排、直流母线电容的布置位置更加合理,可以降低电机控制器的空间占用,以使电机控制器在动力总成上的布置以及安装更加方便,并实现了电机控制器的紧凑化设计、满足了高功率密度的使用要求。
