Abstract: The high frequency power electronic converter is used to drive the fan motor and compressor in household variable frequency air conditioner system. It is of great significance to study the conducted electromagnetic interference mechanism of household variable frequency air conditioners and explore effective suppression strategies for improving the electromagnetic compatibility of air conditioners. Focusing on the conducted electromagnetic interference of the electronic control system of household variable frequency air conditioning, a precise time-domain simulation model of variable frequency drive circuit was established. Through the experimental verification of working conditions, the EMI conduction path of the variable frequency air conditioner system was revealed, and feasible suppression strategies were proposed based on the time-domain simulation model, in order to provide scientific basis and technical reference for the electromagnetic compatibility design of variable frequency air conditioner.

Key words: Variable frequency air conditioner, Conducted EMI, EMC simulation, Suppression strategy
