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.

In this paper, a single switch single stage switched inductor based cuk converter with power factor correction control techniques is proposed. The main features of the proposed converter is low current stress, high voltage conversion ratio, reduction of components, high efficiency, low THD, etc., The operation of the proposed converter is explained in several modes along with the design of the converter. The performance of the proposed converter with different loads such as resistive, battery and motor loads with CC and CV control is analyzed and various factors such as power factor, efficiency and THD are compared. The Simulation work is carried out in MATLAB/Simulink software.
