Abstract

A high voltage gain DC-DC converter is proposed. This converter is capable of stepping up voltages as low as 20V to 400V. The proposed converter can draw power from four independent sources which makes it suitable for applications like solar panels. The proposed converter finds its application in integration of individual solar panels onto the 400V distribution bus in DC micro grids. The proposed converter consists of Diode-Capacitor voltage multiplier stages. The converters achieve a high voltage gain by charging and discharging of the voltage multiplier capacitors. The design and component selection procedures are presented. The simulation of converter is done using MATLAB/SimulinkR2014 software. A 2W, 10kHz hardware prototype of the base circuit with Vin=1V and Vout=20V is also implemented in the laboratory. PIC16F877A is used for generating the control pulse. mikroC software is used for programming the PIC.
