A generic model of a double bridge "AC inductor" based Gyrator-behaved APFC is presented, analyzed and verified by simulation and experiments. Based on the results of the study, a design procedure is developed for specifying the control law and the optimal parameters for ZVS and minimum conduction losses of the proposed APFC. The proposed APFC requires neither line voltage, nor input current sensing circuitry except for line synchronization. The theoretical predictions are well supported by
