Spread-Spectrum Technique Employing Phase-Shift Modulation to Reduce EM Noise for Parallel-Series LLC Resonant Converter

A spread-spectrum technique (SST) has been developed to mitigate an electromagnetic interference in power converters. However, for resonant converters using a pulse-frequency modulation, it is difficult to regulate its output voltage with the SST, because the switching-frequency variation according...
