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.
