Abstract

To improve the robustness of the input voltage and load perturbations of the Boost PFC converter, a synergetic control strategy based on a ultra-local model is proposed. The ultra-local model of the Boost PFC converter is established, the load perturbation is estimated by an algebraic parameter identification technique, and the estimated value of the perturbation is forced to reach the flow surface under the constraint of the convergence time constant by the dynamic evolution law. In addition, macro variables are designed for the system to construct a synergetic control strategy based on an ultra-local model to achieve converter power factor correction while improving the output voltage dynamic response performance. Through the simulation comparison study with the dual PI control, the proposed scheme has better dynamic performance and stronger robustness, which verifies the feasibility and effectiveness of the scheme.
