“…In the bridgeless converter number of 1428 elements conduct during each cycle are reduce as compare to the bridge rectifier. This significantly reduces losses in the circuit as reported in [7][8][9][10][11][12][13][14]. The Bridgeless SEPIC converter offer reduction of cost, light, increases efficiency at the same time maintaining near unity power factor performance.…”

This paper presents bridgeless single ended primary inductor (SEPIC) converter operated in continuous conduction mode (CCM). The converter used in the study offers a lesser conduction loss compared to the other bridgeless SEPIC converter. In order to regulate the required output current and output voltage with high efficiency while achieving high power factor correction (PFC) at the input side, average current mode control (ACMC) is applied. The model is simulated using MATLAB/Simulink and it is found that the converter and the proposed control strategy provide a promising result. The preliminary results obtained from the experimental test-rig shows a good agreement as in simulation. The theoretical analysis of the proposed controller is verified on an output 100V to 300W prototype.

This paper presents a bridgeless SEPIC topology with Power Factor Correction (PFC) to charge electric vehicle battery. The converter offers a few advantages such as reduce total component count and reduction of conduction loss during the conversion AC to DC, hence higher overall system efficiency. The PFC converter operated under continuous conduction mode (CCM) with average current mode control strategy. The model is built and simulated in MATLAB. From the simulation study, it is found that the proposed topology and the proposed control strategy provide a promising result.

“…Among the several bridgeless topologies, the bridgeless boost converter has the disadvantage of high inrush current and high electromagnetic emissions [4]. The bridgeless buck converter increases the total harmonic distortion (THD) and reduces the power factor (PF) [5][6]. Another bridgeless sepic converter topology is presented in [7][8] has relatively high output current ripple.…”

Wind energy conversion system fed EV battery charging system using single phase bridgeless cuk converter is proposed in this paper. PMSG is employed in the WECS to convert the mechanical energy into electrical ac power. In standalone wind energy conversion systems, two stage ac-dc & dc-dc converters are employed to obtain the desired output. The bridgeless cuk converter employed in the proposed charger is a single stage converter which acts as rectifier as well as dc-dc converter. The bridgeless cuk converter converts the ac voltage generated from PMSG into a desired dc voltage for charging the battery of an electric vehicle. Thus, an intermediate stage of power conversion is reduced in the proposed system. Also, a simple output voltage controller is employed in the proposed system to charge the electric vehicle battery with constant voltage irrespective of the wind speed. The proposed off-board EV battery charger is simulated in Simulink environment of MATLAB software and the results obtained are furnished in this paper. The experimental investigation has been carried out in the developed laboratory prototype of the EV battery charging system and the obtained results are furnished in this paper.
