Abstract
In this paper, a theoretical method for analyzing the spectra of modulated control signals for PWM, Quasi-Resonant Converters (QRC), and Resonant Converters (RC) is presented. A comparison of the EMI performance of the QRC, RC, and PWM converters is given based on the spectral bandwidth. Our study shows that, for the same line and load variation, the QRC and RC have better EMI performance than the PWM converter
