Abstract

The invention discloses an electric control assembly and electrical equipment. The electric control assembly includes an electric control board. The electric control board is provided with a system protection ground, a power input terminal for The power output terminal of the motor and the grounding terminal of the motor, among which, the ground wire terminal is connected to the system protection ground; the power filter circuit, the input end of the power filter circuit is connected to the power input terminal, and the output end of the power filter circuit is connected to the power output terminal; EMC filtering circuit, the input end of the EMC filter circuit is respectively connected to the ground terminal of the motor and the ground end of the power filter circuit, and the output end of the power filter circuit is connected to the system reference ground. The invention suppresses the EMC electromagnetic radiation generated by the motor, and improves the overall EMC anti-interference performance of electrical equipment products.

Description

technical field [0001] The invention relates to the technical field of electric control, in particular to an electric control component and electrical equipment. Background technique [0002] EMC refers to the ability of a device or system to operate satisfactorily in its electromagnetic environment without causing intolerable electromagnetic interference to any device in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment during normal operation cannot exceed a certain limit; on the other hand, it means that the equipment has a certain Degree of immunity, that is, electromagnetic susceptibility. [0003] At present, in electrical equipment equipped with a motor, the motor tends to generate extremely wide-spectrum noise during operation, and the noise is easily transmitted to other circuit modules of the electrical equipment through the ground wire, increasing the EMC interfere...
