Electromagnetic compatibility assessment in multiconverter power systems – Conducted interference issues

Electromagnetic Compatibility of Power Line Communication Systems

The power system has been used for communication purposes for many decades, although it was mainly the power utility companies that used low bit rates for control and monitoring purposes. In the last ten years, however, the deregulation of the power and telecommunication markets has spurred the idea of using and commercializing the power networks for a range of new communication applications an...

Susceptibility of ICs to Conducted Electromagnetic Interference

This work is focused on the susceptibility of integrated circuits (ICs) to electromagnetic interference (EMI). The main issue is simulation and measurement on device level and circuit level. The work gives an overview of the overall electromagnetic compatibility (EMC) issues, and shows Direct Power Injection (DPI) measurement technique for conducted electromagnetic interference.

Novel Frequency Swapping Technique for Conducted Electromagnetic Interference Suppression in Power Converter Applications

Abstract: Quasi-resonant flyback (QRF) converters have been widely applied as the main circuit topology in power converters because of their low cost and high efficiency. Conventional QRF converters tend to generate higher average conducted electromagnetic interference (EMI) in the low-frequency domain due to the switching noise generated by power switches, resulting in the fact they can exceed...

Electromagnetic Interference (EMI) in Power Supplies

Increasing power density, faster switching and higher currents forces designers to spend more time both considering the effects of electromagnetic interference (EMI) and debugging a design that has EMI problems but is otherwise complete. This paper explains the different types of EMI and their coupling mechanisms and the existing EMI regulations. The most frequent noise sources, transmission pa...
