![]() ![]() The exclusion method includes a wire drawing method, a partitioning work elimination method, a human body touch method with low voltage and small current, and a region shielding method. The first step : find the method to confirm the radiation source, including the exclusion method, the spectrum analyzer frequency search method, and the component natural frequency analysis method. The EMC rectification six-step method is as follows: the first step to find the confirmation radiation source, the second step filter, the third step absorbing wave, the fourth step grounding, the fifth step shielding, and the sixth step energy dispersion method. There are actually a lot of rectification articles about specific EMC fields. Under certain conditions, it will cause interference, influence and harm to the running equipment and personnel. Interference between various operating electronic devices is mainly related to each other and affects each other in three ways: electromagnetic conduction, electromagnetic induction and electromagnetic radiation. The degree of immunity, ie electromagnetic sensitivity. Therefore, EMC includes two requirements: on the one hand, the electromagnetic interference generated by the equipment in the normal operation process cannot exceed a certain limit on the other hand, it means that the appliance has certain electromagnetic interference in the environment. Electromagnetic Compatility (EMC) refers to the ability of a device or system to operate in its electromagnetic environment and not tolerate electromagnetic interference in any device in its environment. ![]()
