Abstract
This paper presents a chaotic PWM switching technique for a high boost DC-DC converter with a very low ripple at the input current. The use of a choatic PWM allows a reduction of Electromagnetic In (EMI) at the output of power converters by spreading the energy spectrum of the output voltage. In this paper a chaotic PWM, using the Chua oscillator, has been implemented in Matlab for the converter under study and a comparison with a traditional PWM control has been done. A detailed description of the generation of the chaotic carrier is presented and the effect on the output EMI mitigation has been shown.
