Abstract: This paper presents a study on the electromagnetic compatibility (EMC) of an 8 kg washing machine equipped with inverter technology, with a specific focus on disturbance power - one of the key parameters in conduction emission tests - within the frequency range of 30 MHz to 300 MHz. The experiments were conducted in accordance with the CISPR 14-1:2020 standard. The study evaluates the electromagnetic disturbances emitted by the washing machine during typical operation and investigates the mitigation effect of an EMI filter commonly used in some types of home appliances to meet EMC compliance requirements. The effectiveness of the filter is quantified in terms of its ability to reduce conduction emission power. In addition to demonstrating a practical EMI mitigation approach, this research contributes to the broader understanding of emissions from inverter-driven appliances in residential environments. By measuring these disturbances, the study establishes a baseline that can support future research and EMC regulatory developments.

Keywords: electromagnetic interference; EMI; washing machine; disturbance power; filter; conduction emission; power quality.
