Abstract

A chaos control methodology has been proposed for suppressing EMI in DC–DC converters in the former research. In this paper, this method is applied in the power supply ATX as a real practical application, where an external chaotic signal is generated in a control circuit for pulse width modulation (PWM). As compared with the conventional PWM, this methodology has prominent effectiveness in suppressing EMI by spreading the power spectra smoothly over the frequency band.
