Study on Chaotic Soft Switching Forward Converter

摘要：

　　Based on the advantages of the chaotic spreadspectrum technique and the soft switching technique,this paper proposes an effective technique to improve the electromagnetic compatibility(EMC)of the converter.Firstly this paper designs a chaotic soft switching converter.Then it is proved by mathematical derivation that the chaotic soft switching technique can be more effectively in suppressing the electromagnetic interference(EMI)of the converter.In this paper,we derivate the mathematical expressions of the spectrum of the power transistors drain-source current,which work in the PWM mode,the soft switching mode,the chaotic spread-spectrum mode and the chaotic soft switching mode respectively.Finally,the simulation experiment is carried out,and the spectrum of the power transistors drain-source current is obtained.The results show that the chaotic soft switching converter has better EMC performance.
