Modular Bi-Directional Power Flow Converter for Multiple Renewable Energy Sources
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2014, Vol 1, Issue 7
Abstract
This paper presents a new bidirectional dc-dc converter for renewable energy sources with a main objective of building a reliable power source with the available unreliable energy sources i.e., renewable energy sources. Compared to the traditional full and half bridge bidirectional dc-dc converters for the similar applications, the new topology has the advantages of soft switching implementation without additional devices, high efficiency and simple control. These advantages make the new converter promising for medium and high power applications especially for auxiliary power supply in fuel vehicles and power generation where the high power density, low cost, light weight and high reliability power converters are required. The bi-directional dc-dc converter is simulated using ORCAD. The circuit is simulated in the Buck & Boost mode. The simulation results coincide with the results tested experimentally on bidirectional converters. The operating principle, theoretical analysis is provided in this project. The control circuit, power circuit & driver circuit are fabricated on general purpose PCB. The experimental results coincide with the simulation results
