The invention discloses a whole vehicle electric drive three-in-one motor controller, which relates to the technical field of electric vehicles and comprises a box body, an upper cover, an upper end cover, a DC high-voltage wiring harness, a water inlet and outlet nozzle, an integrated PCB (Printed Circuit Board), an AC three-phase output module, a three-phase output copper sheet, a three-phase output copper bar, a heat conduction pad, a ceramic sheet, an IGBT (Insulated Gate Bipolar Translator) pressing sheet, a DC high-voltage adapter, a DC-FILTER component, a DC-LINK capacitor, a single-tube IGBT, an IGBT water cooling plate, a waterproof ventilation valve and the like. The DC high-voltage wiring harness is in high-low-position connection with the DC-FILTER assembly through the DC high-voltage adapter, so that the function of lap joint of a high-position DC voltage connection point of the whole vehicle and low-position high-voltage filtering of the controller is achieved, and the requirements that three-phase output of a motor is far away from the controller and a high-voltage interface of the whole vehicle is too high away from the controller can be met; and meanwhile, a single-tube IGBT driving mode is adopted, and the single-tube IGBT driving mode, the three-phase output copper sheet and the capacitor are integrally cooled, so that the performance requirement is met, the cost of a single power module is reduced to the greatest extent, and the heat dissipation capability of the power module is effectively improved.

    本发明公开了一种整车电驱三合一的电机控制器,涉及电动汽车技术领域,包括箱体、上盖、上端盖、DC高压线束、进出水嘴、集成PCB板、AC三相输出模块、三相输出铜片、三相输出铜排、导热垫、陶瓷片、IGBT压片、DC高压转接座、DC‑FILTER组件、DC‑LINK电容、单管IGBT、IGBT水冷板、防水透气阀等,所述DC高压线束通过DC高压转接座与DC‑FILTER组件进行高低位连接,实现整车高位DC电压连接点与控制器低位高压滤波搭接功能,本发明不仅能满足电机三相输出距离控制器较远和整车高压接口距离控制器过高的需求,同时采用单管IGBT驱动模式并和三相输出铜片、电容一体散热设计,在满足性能要求的同时最大限度的降低了单台成本和有效提高了功率模块的散热能力。
