This dissertation investigates the reduction techniques for conducted electromagnetic interference (EMI) in power electronic systems. The aim of this dissertation is to establish a comprehensive framework for approaches to reduce conducted EMI in power electronic systems. Four essential parts are presented in the dissertation. In the first part, the principle of active EMI filter is thoroughly discussed and a transformer-less feedforward-controlled active filter design is presented. In the second part, a novel switch topology aimed at producing zero common-mode (CM) voltage in voltage source inverter-fed (VSI-fed) motor drives is developed. The proposed switch comes in a compact design and features the merit of plug-and-play. In the third part, an optimized modulation that makes full use of the proposed switch topology in the second part is developed. The optimized modulation has the potential to minimize both the amplitude and frequency of CM voltage in a VSI-fed motor drive. In the fourth and final part, a comprehensive study on conducted EMI suppression in an active front-end (AFE) drive is presented. A practical implementation of random switching frequency for AFE rectifier/converter is developed and tested to demonstrate the effectiveness of random modulation in shaping the conducted EMI spectrum.

Electronics professionals will find this book invaluable when designing power equipment, because it describes in detail how to cope with the problem of electromagnetic interference. The author shows how to meet the exacting US and European EMC standards for conducted emissions. The book includes a wide range of EMI analysis techniques. An important focus is on the energy content of interference transient signals (traditional analysis concentrates on amplitude and frequency). This provides a more accurate picture of the EMI situation. For those who do not want or need detailed analysis techniques, many approximation methods are also provided. These simplified techniques give accurate results for all but the most stringent applications. The book contains several worked examples and an extensive bibliography, and is sure to be useful to electronic design engineers and others who need to meet international EMC regulations and standards. Laszlo Tihanyi has worked on EMC for over 20 years. Formerly Head of the Department of Power Electronics at the Hungarian Research Institute for the Electrical Industry, he focused primarily on solving EMI problems in electronic systems and developing a dimensioning method for power line filters.

As power systems develop to incorporate renewable energy sources, the delivery systems may be disrupted by the changes involved. The grid’s technology and management must be developed to form Smart Grids between consumers, suppliers and producers. Conducted Electromagnetic Interference (EMI) in Smart Grids considers the specific side effects related to electromagnetic interference (EMI) generated by the application of these Smart Grids. Conducted Electromagnetic Interference (EMI) in Smart Grids presents specific EMI conducted phenomena as well as effective methods to filter and handle them once identified. After introduction to Smart Grids, the following sections cover dedicated methods for EMI reduction and potential avenues for future development including chapters dedicated to: •potential system services, •descriptions of the EMI spectra shaping methods, •methods of interference voltage compensation, and theoretical analysis of experimental results. By focusing on these key aspects, Conducted Electromagnetic Interference (EMI) in Smart Grids provides a concise and comprehensive coverage of an extensive subject matter. It constitutes a key resource for any industry practitioners, researchers or system designers with interest in Smart Grids, particularly their electromagnetic compatibility in the conducted EMI frequency range.
