A New four-dimensional chaotic spread spectrum technology for EMI suppression of Zeta converter

This paper introduces an Electromagnetic Interference (EMI) spread spectrum technology with a new four-dimensional chaotic method for the Zeta converter. This paper introduces a novel approach to enhance EMI suppression in power converters. It presents a chaotic pulse width modulation (PWM) method derived from a four-dimensional chaotic circuit, aiming to achieve more effective EMI suppression by improving the spread spectrum distribution at both the switching frequency and its harmonics. Furthermore, a chaotic PWM has been simulated using Multisim for the Zeta converter under study and a comparison has been conducted with conventional PWM control. Finally, the circuit of the new system is implemented and the impact on mitigating output EMI has been shown.
