Provided are an electric valve, a thermal management assembly, and an air conditioning system. The electric valve includes a valve body, a circuit board, and a sensor. The valve body has a passage, and the sensor is connected to the circuit board in at least one of an electric connection mode and a signal connection mode. The sensor is configured to detect at least one of a pressure or a temperature of a working medium in the passage. At least one of the valve body or a housing of the sensor includes a metal portion, and a reference ground of the circuit board is electrically connected directly or indirectly to the metal portion.

Electric valve, heat management assembly and air conditioning system

An electric pump is provided. The electric pump includes a PCB board, where the PCB board is formed with a power input port. The electric pump further includes a common mode filter, where the common-mode filter includes a common mode inductor, and the common mode inductor is arranged close to the power input port; and in a direction perpendicular to a plane on which the PCB is located, no wiring is provided at the common mode inductor corresponding to a wiring film layer in the PCB.

Electric pump

A control system for controlling operation of an execution device is provided. The control system includes a master controller, a microprocessor, and a signal line. The master controller is configured to send a control signal to the microprocessor via the signal line. The microprocessor is configured to send the control signal to the execution device to drive the execution device to operate, acquire, at a time interval, a feedback signal representing an operation state of the execution device, and send the feedback signal to the signal line. The master controller is further configured to acquire the feedback signal from the signal line, determine, from the feedback signal, the operation state of the execution device, and regulate the control signal based on the operation state.

Control system and control method

An electronic pump includes a controller. The controller includes a power input terminal, a printed circuit board, a motor driver and a microprocessor. The power input terminal, the microprocessor and the motor driver are spaced from each other by an electronic clearance and are fixedly connected to the printed circuit board. The microprocessor is electrically connected to the motor driver by the printed circuit board. The motor driver drives a motor to rotate based on a drive control signal from the microprocessor. There is no motor drive circuit composed by discrete components and configured to drive the motor to rotate separately arranged on the printed circuit board between the motor driver and a motor.
