What do EMS and EMI in EMC (Electromagnetic Compatibility) technology refer to respectively?

EMC electromagnetic compatibility technology includes: EMS+EMI

EMS: EMS Electromagnetic Immunity

It refers to the technical means to suppress or eliminate the interference generated by electromagnetic radiation. It can prevent and control the electromagnetic radiation interference generated by electrical appliances, electronic equipment, communication equipment, etc., ensuring the normal operation of equipment, preventing data errors or system crashes, and ensuring the reliability of equipment and systems. EMS electromagnetic immunity usually includes measures such as limiting radiation sources, protecting sensitive equipment, structures, and lines, and eliminating interference to buildings, ground, and surrounding environment.

EMI: EMI electromagnetic interference

It refers to the phenomenon of electromagnetic interference occurring between electronic devices and circuits during operation. Specifically, it describes the situation where electromagnetic waves with higher frequencies (particularly radiant heat sources, high-energy electron beams, microwaves, lightning, etc.) enter and disrupt another circuit or device through wireless or wired circuits. EMI electromagnetic interference can affect the accuracy and reliability of electronic technology applications such as radio communication, computers, and instrumentation, thus necessitating suppression. Techniques such as shielding, filters, and grounding are commonly employed to mitigate EMI electromagnetic interference.

EMC electromagnetic compatibility technology manifests in many aspects of daily life, with the following being the most common:

1. When using electronic devices such as computers, mobile phones, and televisions, avoid using radio equipment and other electronic devices simultaneously, or in situations where mutual interference is significant, try to use equipment with good EMC (Electromagnetic Compatibility) performance.

2. When using household appliances such as air conditioners, refrigerators, washing machines, etc., care should be taken to avoid overuse and excessive proximity to other electronic devices to prevent the impact of EMI (Electromagnetic Interference). Additionally, some household appliances generate high-frequency interference during operation, so it is advisable to choose products with good EMC (Electromagnetic Compatibility) performance.

3. When constructing public facilities such as telecommunication base stations and power lines, EMC (Electromagnetic Compatibility) standards should be adhered to to avoid impact on surrounding residents and other electronic devices.

4. When using medical and industrial equipment, one should adhere to the EMC (Electromagnetic Compatibility) standards to prevent any adverse effects on the health of patients and workers.

In summary, people need to understand the relevant knowledge of EMC (Electromagnetic Compatibility) technology in their daily lives, and pay attention to EMC issues when using electronic devices, household appliances, public facilities, medical equipment, industrial equipment, etc., to ensure their own health and the stable operation of electronic devices.
