Design of Chaotic Soft-Switching Power Converter with High EMC Performance

Chaotic soft-switching technology can better improve the EMC(electromagnetic compatibility) of power converter. However, the switching frequency of power transistors is changed with chaos signal in this technology, so the design of the soft-switching circuit should ensure the converter can work properly in entire switching frequency range. This paper focuses on how to design a soft-switching circuit when converter works in chaotic spread-spectrum mode.
