Implementation of zero voltage switched SEPIC/ZETA bidirectional converter for low power applications using FPGA
This paper presents a derived SEPIC/ZETA bidirectional converter (BDC) with reduced ripple in the noninverted output voltage. This converter is obtained by the fusion of unidirectional SEPIC and ZETA converters that ensures reduced ripple in the inductor currents. The optimal selection of duty ratio enables the proposed converter to operate either in SEPIC or ZETA mode under forward and reverse...
متن کاملLow Power Boost Converter for Portable Applications
Nickel Cadmium batteries are popular because they have a relatively low cost and offer a mature technology. Nickel Metal Hydride batteries have improved volumetric efficiency and have less environmental concerns than Nickel Cadmium. Lithium-Ion batteries are emerging as a leader in the portable market due to their high energy density. Lithium-Ion batteries have the highest initial cost, however...
متن کاملAn Improved Modified Sepic Converter for High-Luminance Lighting LED Lamps
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...
متن کاملBased on a Modified SEPIC Converter with Low Voltage Stress
The boost topology is often the designer's first choice when dealing with PFC front-ends. This topology is well documented in the literature and has obvious advantages like continuous input current and low voltageand current-stress compared to other PFC topologies. The PFC SEPIC converter also has the advantage of the continuous input current but suffers from high voltageand current stress. In ...
متن کاملDesign of Soft Switching Sepic Converter Fed DC Drive Applications
High efficiency DC-DC converters with high-voltage gain have been researched due to increasing demands. A soft-switching single-ended primary inductor converter (SEPIC) is presented in this work. An auxiliary switch and a clamp capacitor are presented in this project. A coupled inductor and an auxiliary inductor are utilized to obtain ripple-free input current and achieve zero voltage-switching...
