Analysis of Boost Converters for PV and Wind in a Hybrid Microgrid

Abstract

This paper presents the analysis of two types of boost converter for PV and Wind in a hybrid Micro-grid. The main aim is to improve the voltage gain capacity of conventional boost converter used in PV and Wind sources for a Hybrid micro-grid. Boost converters are dc to dc converter used to increase the input voltage. Conventional boost converters have low voltage gain capacity with high duty ratio. To eliminate this problem a new three level boost converter which improves the voltage gain capacity with low duty ratio is proposed for PV and a new coupled inductor based boost converter is used for Wind, this also has a high voltage gain capacity. Through this modified converter the voltage gain capacity is increased. The circuit is designed in MATLAB/SIMULINK and results are verified.
