Abstract

In this paper, a novel method based on chaotic dynamics and soft switching control is proposed for the reduction of the electromagnetic interference (EMI) in DC-DC converter. There, a chaotic carrier plays a key role to generate chaotic wave, but a practical design is not yet available in literature. Therefore, to design a chaotic carrier, a practical design based on a chaotic mapping and sawtooth wave generator is proposed to covert the periodic sawtooth wave to the chaotic one. Simulation results show that the EMI of the DC-DC Boost converter has been much reduced due to the total energy more evenly spreading over the frequency band and the reduced energy loss. It is also found that the efficiency of the DC-DC Boost converter is improved as compared with the hard and soft switching PWM controls. © 2008 IEEE.
