The invention discloses a support capacitor and a dual-motor controller, and relates to the technical field of dual-motor controllers. Wherein the supporting capacitor comprises a capacitor shell, a positive electrode copper bar, an insulating layer, a capacitor core body, a negative electrode copper bar and an insulating layer which are sequentially stacked from bottom to top; the dual-motor controller is composed of a supporting capacitor and a parallel tube IGBT module, the parallel tube IGBT module is composed of a plurality of parallel tube IGBT assemblies, each parallel tube IGBT assembly is formed by connecting a plurality of IGBTs in parallel and welding the IGBTs through an IGBT driving plate, each parallel tube IGBT assembly further comprises a copper busbar, and each IGBT is connected with the copper busbar through a screw; the capacitor core body is connected to the IGBT through a positive electrode copper bar and a negative electrode copper bar which support the two sides of the capacitor. According to the embodiment of the invention, the supporting capacitors are redesigned, and the IGBTs are used in parallel, so that the problems that the number of parts is large, the assembly is complex, and the size is large are solved.
