Abstract
This paper analyzes the electromagnetic interference (EMI) suppression for Dual-Bridge Series Resonant DC/DC Converter (DBSRC) based on chaotic pulse width modulation (CPWM) and compares the performance of four kinds of one-dimensional chaotic maps. Bi-Directional DC/DC converter has a bright future and it is gaining more attentions in electric vehicle, energy storage system, renewable energy system, etc. In medium Power and high power systems the dual-bridge series resonant DC/DC converter is widely used. High frequency and high power converter usually causes strong electromagnetic interference. The Amplitude of harmonic current at switching frequency and its multiple frequency is particularly high, which makes it hard to filter. In recent years, EM I suppression based on CPWM has gradually become a popular direction. This paper provides reference for chaotic maps' selection by analyzing their performance.
