Most of the power electronic equipments are operated with dc supply. For reliable and stable operation, dc supply should be regulated. The regulation can be performed using buck, boost, Cûk, Sepic, Flyback regulators. Except single phase rectifier with resistive load all other rectifiers input currents are non sinusoidal in nature. This front end current distortion of rectifier converter leads ...

This work presents a new system configuration of the front-end converter stage for a hybrid wind/photovoltaic energy system. The aim of this project is to implement the high efficiency converter for the wind and solar hybrid system. In proposed system, consists of bridgeless SEPIC and converters zeta and mppt controllers both the sources to supply the load separately or simultaneously depending...

Received Nov 1, 2014 Revised Mar 4, 2015 Accepted Apr 1, 2015 A Single Phase Switched Reluctance Motor is more popular in many industrial purposes for high speed applications because of its robust and rugged construction. For low cost and variable speed drive applications SRM are widely used.Due to doubly salient structure of motor, the torque pulsations are high when compared to other sinusoid...

This article investigates the gallium nitride based bridgeless dual single-ended primary inductor converter (SEPIC) power factor correction (PFC) with full input voltage range zero-voltage-switching (ZVS) turn- on for application of step down ac–dc converter. The operation principle Dual-SEPIC ...

The efficiency and lifetime of light-emitting-diode (LED) lamps are approaching and exceeding that of fluorescent lamps. LED light sources are finding more applications than conventional light bulbs due to their compactness, lower heat dissipation, real-time color changing capability and most importantly, long life which is much longer life than that of conventional offline power converters. In...

In this paper a new LED driver and its controller are conceived realized and experimentally validated. It presents several advantages compared with existing counterparts: First it uses a single converter while most of the existing drivers are based on a two-converter architecture. In the proposed approach the average current through the LED is directly regulated. The proposed driver is built ar...
