Two switch three phase ĆUK regulated rectifier
Abedin, Amina Hasan; Choudhury, Mohammad Ali A.Shoukat
A three phase Vienna/Modular-Boost rectifier provides only boost voltage gain regulation using three single phase PFC controller to achieve power factor correction and input current waveform improvement. A Buck-Boost voltage gain regulated two switch three phase ĆUK AC-DC converter is considered in this paper with only output voltage feedback control. The proposed circuit has fewer active and passive components. Reduction is done on controlled switches and diodes of the power circuit and also on sensors, isolation and base drive supply circuits. The proposed three phase boost-buck PFC rectifier can easily be explained and analyzed on per phase basis. The concept of ĆUK DC-DC conversion can be applied on AC-DC converter operation to describe the circuit operation.

Output regulated one-switch three-phase boost and boost-buck (SEPIC) PFC rectifiers
Abedin, Amina Hasan; Bashar, Khandaker Lubaba; Islam, Samia M.Naeemul; Choudhury, Mohammad Ali A.Shoukat
New output regulated one-switch boost and boost-buck three phase rectifiers are presented in this paper. Proposed three phase ac-dc converters have power factor correction (PFC) and input current shaping facility in one power stage. Use of minimum number of control switch in each proposed circuit reduces conversion circuit components, drivers and drive isolation circuits, sensors and control circuits. The operation and performance of the circuits are illustrated by simulation and experimental results. Both circuits are robust in terms of operation, maintenance, control and satisfactory efficiency of conversion. Input sides of the converters being of boost topology, they are capable of being controlled like single phase boost PFC rectifiers. The converter with boost-buck voltage gain characteristic is derived from DC-DC SEPIC converter.

A single phase SEPIC AC-DC converter with improved power factor and input current THD
Hossain, Mohammad Rubaiyat Tanvir; Abedin, Amina Hasan; Choudhury, Mohammad Ali A.Shoukat
A new topology of single-phase SEPIC (Single Ended Primary Inductor Converter) AC-DC converter with low input current THD and high input power factor is proposed. Instead of using a single phase rectifier followed by a boost DCDC converter, or using a bridge rectifier with two diodes and two switches, the rectifier's input is chopped at high frequency during positive and negative cycles by a single bi-directional switch to get step-up/step-down AC-DC conversion. Total Harmonic Distortion (THD) of the input current of the proposed circuit with small input current filter is low. Input power factor and the efficiency of conversion of the circuit are high. No additional control is required to achieve the advantages.

A modular one-switch three-phase Single Ended Primary Inductor (SEPIC) rectifier

An input switch based modular Single Ended Primary Inductor (SEPIC) three phase AC-DC converter is proposed in this paper. The proposed rectifier has the advantage of step-up/down voltage gain with boost input stage. Input boost stage allows input current shaping accompanied by power factor correction. The topology will also provide possible capacitive isolation of input/output sides of the converter. The rectifier has minimum number of controlled switch, less number of diodes, fewer controller components and driver, isolators, sensors and heat sinks than other input switched three phase rectifiers. As a result, the proposed rectifier will be easy to operate, maintain, reliable in operation, light weight, compact and cost effective. The proposed three phase SEPIC rectifier is presented in this paper with its typical simulation and prototype's experimental results.
