This work focuses on the field of electromagnetic compatibility (EMC) in household electrical appliances, power tools, and similar equipment. The main objective of the work is to compare the differences between various editions of EMC-related standards, primarily EN 55014-2 and the IEC 61000-4-x series, and to analyze additional requirements imposed by manufacturers to ensure product reliability and compliance in modern electromagnetic environments.
The first part of the thesis provides a theoretical background on EMC, its importance, and its role in ensuring the proper functioning of electronic devices without causing interference. An overview of relevant harmonized standards is presented, describing the methodology for immunity testing, including electrostatic discharge (ESD), radio-frequency electromagnetic fields, fast transient disturbances, surge pulses, conducted disturbances, and voltage dips.
The experimental section presents the results of EMC immunity testing conducted according to current standard requirements. Furthermore, a detailed analysis of differences between various standard editions is provided, focusing on the expansion of test frequency ranges, updates in measurement methods, and revised performance criteria. The thesis also examines additional manufacturer-specific requirements, which often go beyond minimum regulatory compliance. These include higher ESD test voltages, extended RF immunity testing, and long-term stress tests that aim to improve overall product quality and user experience.
The results indicate that continuous updates to EMC standards are necessary due to the increasing complexity of modern electromagnetic environments, especially with the integration of IoT technologies, 5G networks, and wireless communication. Additionally, the findings show that stricter manufacturer requirements enhance device reliability, minimize product failures, and ensure compliance with demanding global market expectations.
