Abstract

There are more chaos phenomena in boost circuit, which make the system working in the unsteady state frequently. As the final control signal, the change of duty cycle reflects the stable operating characteristics of boost circuit. Based on the continuous conduction mode (CCM) of boost circuit, the duty cycle criterion of circuit stability is deduced, and the change characteristics of duty cycle are studied, the basic principle of resonant parameter perturbation control is analyzed in this paper. With the mathematical model of boost circuit, the characteristics of resonant linear parameter perturbation modulation and sinusoidal parameter perturbation modulation are analyzed while the stability criterion is satisfied and dissatisfied, and it provides the feasible strategy and the method for Boost circuit stability design and control.
