A general approach to evaluate the converter dynamics versus the necessary dynamics for operation as an active power factor corrector is introduced. A simple criterion is developed in the time domain that enables characterization of converter topology and component values for APFC applications. This criterion can be incorporated in the design of APFC circuits to define the upper bounds on reactive component values whereas the lower bound is derived from the ripple requirements. The input current distortions caused by a converter whose characteristics do not met the minimum requirements are calculated for a boost converter, which is chosen as a particular example.
