A Fuzzy controlled high gain DC–DC converter for renewable power generation

Journal of Intelligent & Fuzzy Systems

This manuscript discuss about the various DC-DC converter configurations with high voltage conversion ratio utilized in DC micro-grid structures. The presented DC-DC converter topologies play a major role globally in the power generation sector including micro-grid, because of its decreased number of semiconductor devices, maximum conversion efficiency, small in size and cost of manufacturing is less. In this manuscript the DC-DC converter are categorized in to isolated and Non-isolated topologies. The first group topography works with the presence of transformer and the second group works without the transformer. These converters are capable to provide the various stages of output range. Researchers utilize these converters in the area of renewable energy generation, electric vehicle, micro sources, charge pumping applications etc. Hence they also work to improve the efficiency and reliability with reduction in components numbers and economical aspect. In this manuscript, the various topography of DC-DC converter topologies utilized in micro-grid are reviewed and comparison is made based on voltage conversion ratio, duty ratio, efficiency along with the basic operating principle. This review also reveals the research gaps, current trends, and challenges in the last part. © 2017 Elsevier Ltd

An overview of high voltage conversion ratio DC-DC converter configurations used in DC micro-grid architectures

To meet the ever increasing electrical energy demand, energy conversion from PV sources is gaining prominence. When used in conjunction with existing power system network, the energy extracted from the renewable energy sources can be utilized to electrify remote areas also. The advancements in DC-DC converter topologies and inverter control strategies have led to the wide emergence of grid tied PV systems. The efficiency at which power is fed to the grid hinges largely on the proper choice and performance of the DC-DC converter stage. Hence, there is a compelling need to thoroughly review the performance of existing DC-DC converter topologies. In this paper, a comprehensive review on the evolution and design aspects of High Gain High Power (HGHP) DC-DC converters employable for solar PV fed system is presented. A simple and generalized strategy to derive high gain high power DC-DC converters has been developed and presented. The salient features of five novel converter topologies that have been derived by using the proposed strategy are elaborated to illustrate the validity of the adopted synthesis methodology. The salient features and the feasibility of connecting the derived topologies to the DC grid/micro grid are highlighted. © 2016 Elsevier Ltd

Non isolated high gain DC-DC converter topologies for PV applications – A comprehensive review

The output voltage available from renewable sources like photovoltaic panels, fuel cells and battery banks are too low to be practically utilised. Therefore, the available voltage must be stepped up considerably before connecting to the load. In this paper, a novel topology, which consists of two interleaved stages and five voltage multiplier cells, is presented. The topology is derived from a classical boost converter and utilises two switches, two inductors for the interleave stage,12 diodes, 12 capacitors and one voltage lift capacitor to provide a voltage gain of 14. In general, a topology that provides a gain (N + 2) times that of a classical boost converter utilises (2N + 2) diodes and (2N + 2) capacitors along with a voltage lift capacitor. The primary feature of this topology is its capability to provide high-conversion ratio without using a transformer; additional features are, continuous input current, moderate duty cycle operation and modularity. Experimental results obtained from a 100 W, 24 V/336 V prototype demonstrate the feasibility of the converter and validate the converter design. © 2014 Inderscience Enterprises Ltd.
