Quantification analysis of input/output current facilitates the optimal design of the interleaved PFC boost converter. This paper presents a method to calculate these currents both in switching cycle and mains half cycle for interleaved PFC AC/DC boost converter, which is valid for this converter with arbitrary number of phases operating at continuous ...

Turn-on turn-off zero-current-switching converter in power factor correction (PFC) application
2011 IEEE International Symposium on Industrial Electronics, 2011This paper presents a turn-on turn-off zero-current-switching (ZCS) converter in a PFC boost application. The applied soft-commutation cell is capable of providing ZCS operation keeping the main switch current equal to the input current. Substituting the typical PWM cell found in classics power converter structures by the presented ZCS cell with three ...

Integrated PFC and DC/DC stage for power factor correction and output voltage regulation
2016 International Conference on Computer, Electrical & Communication Engineering (ICCECE), 2016An integrated PFC and DC/DC stage with reduced voltage stress across the switches is proposed for power factor correction and output voltage regulation. The paper aims to converter gives AC to DC rectification, input power factor correction and output voltage regulation that all will takes place into a single stage. The advantage of PFC and DC/DC stage

Coupled inductor‐based buck power factor correction (PFC) converter with soft switching
International Journal of Circuit Theory and ApplicationsSummaryIn this study, couple inductor‐based buck power factor correction (PFC) converter is designed to mitigate dead zones of the converter. To minimize switching losses, all switches are controlled using a soft switching method, eliminating the need for snubber circuits.

Studies of a novel AC-DC converter with three-phase power factor correction (PFC)
ISIE'2000. Proceedings of the 2000 IEEE International Symposium on Industrial Electronics (Cat. No.00TH8543), 2002A novel three-phase major circuit topology is proposed in this paper and its circuit design is also given. Its characteristic is that specific PFC integrated circuit is not applied in this AC-DC converter, there are less circuit components and its power factor is very high.

In this paper a modular three phase power factor corrections (PFC) structure is proposed. The proposed topology employs two single phase PFC stages that are independently controlled. To secure the single phase PFC independent operation; an electronic phase shifter (EPS) is employed to modify the three phase input voltages to two single phase input ...

IEEE Transactions on Power Electronics, 2013
The proposed perturbation on-time technique suppresses total harmonic distortion (THD) and, thus, improves the power factor in the power factor correction (PFC) controller. Besides, the adaptive control of the minimum off time by the proposed inhibit time control can improve efficiency even at low ac input voltage.
