In this paper, an approach to generate robust control algorithm for the single phase PFC boost converter is presented. This control rules provide fast output response while maintaining high power factor. This approach is based on derivation of the control functions for both current loop and voltage loop which is multi-loop control structure.
Designing of the control parameters are based on the required transient and the steady-state responses. Due to application of feedback linearization the performance of the of this control scheme is robust under all practical conditions. This method eliminates the nonlinearity and the dependence of the error dynamics on the input disturbance.
Experiments are conducted to evaluate the control performance.
