Coupled Inductor Based Single Phase CUK Rectifier Module for Active Power Factor Correction

Closed Loop Bridgeless CUK Rectifier for Power Factor Correction

A step-up bridgeless single phase ac-dc power factor correction (PFC) rectifier based on Cuk topology is proposed for high voltage battery charger application. The proposed topology consists of common input stage and parallel output stages. It utilizes one control signal over the whole line cycle. In addition, the proposed converter exhibits low inrush current and low magnetic emissions as clas...

Power factor improvement using DCM Cuk converter with coupled inductor - Electric Power Applications, IEE Proceedings-

Most of the power factor regulator topologies in continuous conduction mode result in bulky magnetics, and in discontinuous conduction mode result in high harmonic content. To solve these problems a Cuk topology is presented in discontinuous conduction mode (DCM) with coupled inductors for power factor regulation, the unique feature exhibited by the converter that makes the converter better tha...

New DCM Operated Single Phase Bridgeless Cuk Derived Converters for Power Factor Correction

This paper presents a power factor corrected (PFC) new bridgeless (BL) Cuk Topologies for low power applications. A BL configuration of Cuk converter is proposed which eliminates the usage of diode bridge rectifier at the front end of the PFC converter, thus reducing the switching and conduction losses coupled with it. This new BL Cuk converter has two semiconductors switches. The current flow ...

Power Factor Correction in Permanent Magnet Brushless Dc Motor Drive Using Single-phase Cuk Converter

Permanent magnet brushless DC motor (PMBLDCM) drives are being employed in many variable speed applications due to their high efficiency, silent operation, compact size, high reliability, ease of control, and low maintenance requirements. These drives have power quality problems and poor power factor at input AC mains as they are mostly fed through diode bridge rectifier based voltage source in...
