Abstract:
An electric pump. The electric pump comprises a PCB board, wherein the PCB board is formed with a power source input port. The electric pump further comprises a common-mode filter, wherein the common-mode filter comprises a common-mode inductor, and the common-mode inductor is arranged close to the power source input port; and in a direction perpendicular to a plane on which the PCB board is located, a wiring is not provided at the common-mode inductor corresponding to a wiring film layer in the PCB board. By means of the technical solution of the present invention, a common-mode signal in a power source signal transmitted by means of a power source input port is effectively filtered, thereby enhancing the electromagnetic compatibility of a PCB board, and enhancing the electromagnetic compatibility of an electric pump.
