    摘要: 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.

    摘要: Disclosed are a control method and a control system. A valve closing position of a valve device (1) can be controlled according to the current flow direction or working mode of a refrigerant. The stroke of the valve device (1) from a fully-opening position to a fully-closed position is defined as a total valve closing stroke. When the flow direction of the refrigerant is a forward direction, the valve device (1) is controlled to run to a first valve closing position, and when the flow direction of the refrigerant is a reverse direction, the valve device (1) is controlled to run to a second valve closing position. The first valve closing position is different from the second valve closing position, and in this way, wear caused by valve closing can be reduced.

    摘要: A control system (2) and a control method, used for controlling a motor (31). The control system (2) comprises a central processing module (22) and a drive control module (23). In a period in which a voltage is not applied to any phase coil of the motor (31), the drive control module (23) collects voltages of the phase coil, converts the voltages of the coil into digital signals and stores the digital signals. The central processing module (22) reads the digital signals from the drive control module (23), accumulates the digital signals to obtain an accumulated value, and determines the operating condition of the motor (31) according to a relationship between the cumulative value and a preset threshold, thereby improving the reliability of the motor control.
