Investigation and analysis of interleaved DC-DC converter for solar photovoltaic module [articol]

Abstract

Solar energy is derived from solar radiations that are replaced constantly. A Conventional dc-dc Converter is suggested for very effective solar energy systems. It is not capable for obtain a high voltage gain even extreme duty cycle maintain the triggering circuit diagram. In order to increase the voltage gain for the new Boost converter from the solar power application. This paper presents a novel High Step-up Ratio Interleaved DC-DC Converter for Solar Photovoltaic Module. The advantages of interleaved boost converter related to the conventional boost converter are low input current ripple, high efficiency, faster transient response, reduced electromagnetic emission and improved reliability. The output voltage is high and voltage stress across the active switch is minimized and output ripples also minimized. The waveforms of input, inductor current ripple and output voltage ripple are achieved using MATLAB/Simulink
