Integrated Coupled-Inductor and Diode-Capacitor for a High Voltage Gain Dc-Dc Converter

Abstract: This project aims to design and implementation of high efficiency and high step –up non-isolated DC-DC converter. The high power non –linear loads and low power loads produce voltage fluctuations, harmonic currents and an imbalance in network which results into lower Power factor operation of power supply. There is a need of improved Power factor and reduced harmonic current in input line. In this project high step-up boost converter with coupled inductor has been introduced to regulate the line voltage. The DC power to this proposed converter is derived from AC lines by using diode bridge rectifier with filter. The main objective of design and implementation is to improve source side power factor with reduced harmonic content and also to improve the voltage conversion ratio at the DC load side.
