Analysis, Simulation, and Comparison of Multi-Module Interleaved DC-DC Converter for Hybrid Renewable Energy Systems

Abstract

Renewable energy systems are placed to become the best power solution for many applications. Recently, a multi-sources systems were used widely as a reliable and flexible power system construction, these systems used the multi-input converter (MIC) as a replacement of several single-input converters which leads to a simpler and lower cost circuit. In this paper, a multi-input converter (MIC) to process multi-source power is proposed and compared in different topology, a three common structure of these converters based on interleaving technique and using Adaptive Delta Modulation (ADM) loop as a controller was presented. While each of these converters operate at interleaving mode, better performance can be achieved and the size also is reduced. Analysis of the converters are carried out in order to achieve the required system stability and to improve the dynamic performance. Simulation results are presented to illustrate the advantages and performance comparison of the proposed converters. The ADM control loop provides a number of features like very fast response and high stability with input voltage or output load variation which also maintained.
