This work is devoted to investigation of the power factor corrector's (PFC) dual-loop control systems. Two control systems of PFC with different structures were studied: with main voltage and main current feedbacks. A subharmonic stability analysis has been performed for PFC based on conventional boost converter. However, the expression for input current of the storage inductor can be used for PFC based on zero-current switching quasi-resonant boost converter. The stability condition at the main subharmonic frequency has been formulated. The calculation results of the voltage change rate at the current loop input and factor of pulsations have been presented. The PFC subharmonic stability margin has been assessed and condition for choosing the reference voltage amplitude has been proposed.

The problems, devoted to power quality and particularly power factor correction, are of great importance nowadays. The key requirements, which should be satisfied according to the energy efficiency paradigm, are not limited only by high quality of the output voltage (low total harmonic distortion), but also assume minimal power losses (high efficiency) in the power factor corrector (PFC). It could be satisfied by the use of quasi-resonant pulse converter (QRPC) due to its high efficiency at high switching frequency instead of the classical pulse-width modulated (PWM) boost converter. A dynamic model of QRPC with zero current switching (ZCS) is proposed. This model takes into account the main features of QRPC-ZCS as a link of a PFC closed-loop system (discreteness, sharp changes of parameters over switching period, input voltage impact on the gain). The synthesized model is also valid for conventional parallel pulse converter over an active interval of commutation. The regulator for current loop of PFC was synthesized based on digital filter using proposed model by the criterion of fast acting.
