Analysis, Design and Simulation of High Step-Up Developed DC-DC Converter

Abstract

High Step Up - High voltage gain converter is becoming the most productively converter now a days mostly in hybrid technology, mobile technology and for other portable devices that are in need of high voltages from low voltage input. Furthermore these converters are widely used in battery charging that includes Fuel cells as well. This Thesis discusses Simulate and proposed advancement in Developed High Step up Voltage DC to DC converter. Detailed analysis on Integration of Double Boost – SEPIC and CUK has been proposed. Proposed Topology contains multiple inductors with one controlled switch that will make a control mechanism useful for every application. Secondly voltage stresses across silicon conductor devices are very low. Conduction losses will also be reduced due to low voltage Stress. Reverse recovery current problem is also in under consideration of this thesis that will enables the use of Schotkey rectifiers. The keen purpose of the topology is to obtain the maximum output voltage with maximum voltage gain and less conduction losses reducing input ripple current. Without disturbing characteristics of Topology. A detailed analysis has been done on every converter separately and by integrating all converters to check the results. Mathematical equations are also derived for better understandings and simulation results are obtained as well.
