Cuk Converter

In this paper, analysis and design of a novel single phase AC-DC CUK converter circuit has been proposed where Power Factor Correction (PFC) controller scheme has been used in order to obtain better performance than conventional converters. Closed loop technique is applied to the bridgeless converter in order to achieve low input current, Total Harmonic Distortion (THD) at input AC mains along with near unity power factor. Performance comparison between open loop and closed loop of the proposed converter is made without filtering. The problems arise with open loop is sufficiently minimized by using power factor correction controller. The performance comparison between proposed and conventional CUK AC-DC converter operating in Continuous Conduction Mode (CCM) is made based on circuit simulations using PSIM softwere.

This paper presents about the comparison between single-phase PFC Cuk converter and bridgeless PFC (BPFC) Cuk converter for low power application. This study attempts to investigate the characteristics of conventional and bridgeless PFC Cuk converter structures with three different output voltages and verified by the simulation results. The BPFC Cuk converter provides a lower Total Harmonic Distortion (THD) of input current than the conventional PFC Cuk converter. However, the conventional PFC Cuk converter has advantage of less maximum current stress at components compared to the BPFC Cuk converter. Conventional and BPFC Cuk converter can achieve an approximately unity power factor (PF).

This paper deals with PFC-isolated Zeta converter fed LED drive to overcome the power factor problems. The proposed circuit topology consists of diode bridge rectifier and isolated Zeta converter with high frequency transformer. A single –phase supply is used to feed a DBR followed by a filter to avoid any switching ripple in DBR and the supply system. An isolated Zeta converter is operated to work under DCM mode. This combination of DBR and PFC converter is used to feed a LED drive. This converter is simulated in MATLAB platform. This converter provides better results such as unity power factor and less current harmonic distortion.

In this paper closed loop analysis of Single phase AC-DC Bridgeless Single Ended Primary Inductance Converter (SEPIC) for Power Factor Correction (PFC) rectifier is analyzed. In this topology the absence of an input diode bridge and the due to presence of two semiconductor switches in the current flowing path during each switching cycle which will results in lesser conduction losses and improved thermal management compared to the conventional converters. In this paper the operational principles, Frequency analysis, and design equations of the proposed converter are described in detail. Performance of the proposed SEPIC PFC rectifier are carried out using Matlab Simulink software and results are presented.
