In the first part of the paper, the requirements of circuits containing linear inductors, capacitors and ideal switches for the synthesis of power-factor-correction (PFC) converters are examined. Sufficient conditions for achieving PFC are stated in terms of the circuit topology and the switching sequence. Various topologies, from the simplest buck, boost, and buck-boost converters to fourth-order Cuk, Zeta and SEPIC converters, are examined in the light of these topological conditions. In the second part of the paper, the general configuration of power supplies that provide PFC and voltage regulation will be discussed. It consists of two simple power stages forming a three-port network which is terminated to an input voltage, a storage capacitor and an output load. The various possible arrangements of the two constituent power stages will be discussed with emphasis on minimizing the amount of power that is processed serially by the power stages.
