Electromagnetic Compatibility (EMC) refers to the ability of electrical equipment or systems to operate without causing electromagnetic interference to their environment or being susceptible to such interference. As a critical quality benchmark, EMC compliance should be addressed during the initial product design phase through cost-effective countermeasures. By definition, EMC comprises Electromagnetic Interference (EMI) and Electromagnetic Susceptibility (EMS).

Household PV-storage-charging products integrate various power electronic devices such as photovoltaic inverters, power conversion systems (PCS), and charging modules. Their internal high-frequency switching actions (e.g., IGBT switching frequency harmonics) and complex topologies are prone to generate electromagnetic interference (EMI). Core components within such equipment (such as high-frequency switching transistors, inductors, capacitors, and control circuit boards) produce high-frequency harmonics and switching noise during operation, which may form electromagnetic disturbances through conduction or radiation paths.
With the rapid development of 5G communication technology and the Internet of Things (IoT), wireless interconnection functions of electronic devices have become widely popular in smart home appliances, leading to an increasingly complex electromagnetic environment. Household appliances (such as refrigerators, air conditioners, washing machines, etc.), due to the integration of wireless modules like Wi-Fi and Bluetooth, may not only generate high-frequency noise or conducted interference during operation but also need to resist electromagnetic radiation from mobile phone base stations and other smart devices, making their Electromagnetic Compatibility (EMC) issues increasingly prominent.
