ABSTRACT:This paper proposes a model of the bridgeless PFC (Power Factor Correction) boost rectifier for control purposes based on an averaged small-signal analysis. From circuital laws, four operation modes are defined and explained, ensuring a relationship of physical variables in the converter. Based on the proposed model, two-loop cascade control structures composed of Proportional-Integral (PI) lineal controllers are proposed. Design consideration for dimensioning reactive elements is included, providing minimum values for their inductance and capacitance. Implementation of a laboratory prototype of 900 W and experimental results are presented to validate and reaffirm the proposed model. Experimental results demonstrate that the use of the bridgeless PFC boost converter model allows the Power Factor (PF) to be elevated up to 0.99, to reduce the THD i (Total Harmonic Distortion of the Current) to 3.9% and to control the DC voltage level on output. Compliance of standards of power quality EN 61000-3-2 (IEC 1000-3-2) are experimentally verified.

“…Therefore, by using (6) through (14), the average inductor current over the k th switching cycle can be calculated. Similar to the relationship between (2) and (3), the notation k in (6) through (14) can be eliminated to derive the filtered inductor current, If, because the switching period is much smaller than the AC line period. Because the resonance between L and Cds is taken into account, the equation of If is no longer as simple as the one shown in (5), which is directly proportional to the utility voltage.…”

This paper proposes a line current distortion compensation method, which is a fusion of the conventional variable on-time (VOT) control and the average current mode (ACM) control, for DCM/CRM boost PFC converter with zero current switching (ZCS)/ zero voltage switching (ZVS)/ valley switching (VS)/ switching frequency limitation (SFL) functions. In this paper, the mathematical analyses of the line current distortion for the DCM/CRM boost PFC converter with ZCS/ZVS/VS/SFL functions are also derived to explain the causes of the line current distortion. In order to increase efficiency, the ZVS/VS/SFL functions are needed but the line current will be further distorted. To compensate the distorted line current, the ACM-based VOT (ABVOT) control for the DCM/CRM boost PFC converter is proposed. In addition, the constant-on-time-based noise-immunity S/H method is proposed to replace the multiplier, which is always needed for the conventional ACM-based control. The performance of the proposed ABVOT control with S/H method will be demonstrated by simulation and experiment results.Index terms -power factor correction (PFC), variable on-time (VOT), average current mode (ACM), multiplierless.

Traditional characterization of semiconductors switching dynamics is performed based on clamped inductive load measurements using the double pulse tester (DPT) configuration. This approach is valid for converters operating in continuous conduction mode (CCM), however in boundary conduction mode (BCM), if valley switching detection is used, the amount of energy recovered from the semiconductor output capacitance and the converter switching frequency need to be accurately calculated. This paper presents a characterization and evaluation procedure for conventional power factor correction circuits operating in CCM and BCM.
