Design and Implementation of Step-Up DC-DC Converter by Cascading Cockcroft Walton Voltage Multiplier for Hybrid System

Abstract

this paper presents the use of a stepupdc-dc converter by cascading cock croftwalton voltage multiplier for a hybrid system. The hybrid renewable energy system used is a combination of as olar panel and a fuel cell. the conventional method isto use a converter increase the voltage and further uses a transformer to increase the voltage level of the output. The p ro p o s ed converter topology used is boost converter cascaded with an n-stage cockcroft-walton voltage multiplier. the number of stages of the voltage multiplier increases the output level of the stepupdc-dcconverter which drives the load. The converter-voltage multiplier module provides continuous conduction with the voltage stress on cascaded capacitor-diode and switches being reduced. The output voltage obtained can be used in highvoltage applications .the simulation of the entire topology for hybrid system was done using matlab software.
