Abstract A novel chaotic pulse‐width‐modulation (PWM) boost converter has been previously proposed to reduce electromagnetic interference (EMI) in DC–DC converters, where the circuit design and simulations have been conducted, but the problems such as the mean value estimation of state variables for circuit parameter design, the ripple estimation of the input current and the stability analysis have been remained to be addressed in this paper. Here, a mean value estimation method is first proposed, which is used to estimate the mean values of state variables of chaotic PWM boost converters for facilitating the circuit parameter design and selection of circuit components. Although ripples are slightly increased, caused by adopting chaotic carriers, the DC–DC converter with reduced EMI is still stable under the chaotic PWM control. This work provides a theoretic verification of the effectiveness and practicability of the proposed chaotic PWM DC–DC converters. Copyright © 2010 John Wiley & Sons, Ltd.
