| Abstract |
Traditional pulse width modulated (PWM) power converter operates on a constant switching
frequency. This frequency is also presented in the electromagnetic interference (EMI) -spectrum of the
converter. During the last decade, intensive study of EMI-reduction techniques, including spread
spectrum technology, in the field of power electronics has been made. Selected control strategy also
effects on the generated EMI spectrum. In this paper, a comparison between EMI-noise effects of
fixed frequency, PID-controlled PWM and sliding mode –controlled (SMC) converter has been done.
Both simulation and experimental results are presented. |
