Enhancing common-mode suppression in microstrip differential lines by means of chirped and multi-tuned electromagnetic bandgaps (EBGs)

This paper presents common-mode suppressed microstrip differential lines based on chirped electromagnetic bandgaps (EBGs). To achieve common-mode suppression in a wide band, the common-mode impedance is modulated following a sinusoidal chirping, whereas the differential-mode impedance is kept unaltered, thus ensuring that the line is transparent for that mode. The result is a differential line ...

EMC’04/Sendai COMMON-MODE NOISE REDUCTION TECHNIQUES FOR SWITCHED-MODE POWER CONVERTERS

In various kinds of switched-mode power converters, conducted noise due to switching operation frequently causes interference with other electronic equipment. This paper focuses on the common-mode conducted noise generated in switched-mode power converters and presents three examples of noise reduction techniques. First, the common-mode conducted noise is reduced in a common-source type active-...
