The method of resonant parametric perturbation is a simple non-feedback chaos control means. It is such a suitable control method for controlling chaos in non-autonomous systems that we are inspired to study its applications for chaos control in current controlled Boost converter. Furthermore, the method of resonant parametric perturbation is optimized by selecting the best perturbation phase, so as to achieve the best chaos control results. These relative applications (with or without optimization) in Boost converter can be analyzed theoretically, and the influence induced by variable circuit parameters on the effective perturbation can also be calculated or predicted.
