Abstract: In this paper, a generalized approach for the systematic generation of robust control rules for the boost power factor correction converter is presented. Based on a cascading multiloop control structure, a unified approach for deriving the control functions for the inner current loop and the outer voltage loop is proposed. The resulting control provides unity power factor and regulated average output voltage with fast transient response. The control performance is robust under all practical conditions as a result of the application of feedback linearization. This method eliminates the nonlinearity and the dependence of the error dynamics on the input disturbance. The control parameters can be designed according to the desired steady-state and transient response performances. The resulting control rules are readily implemented in analog circuitries. Experiments are conducted to evaluate the control performance.
