Analysis of Multiport Dc-dc Converter in Renewable Energy Sources
Multi-port DC-DC converter has attracted special interest in applications where multiple energy sources are used. In this project, a three-port converter with three active full bridges, two LCC resonant tanks, and a three-winding transformer is proposed. It uses a single power conversion stage with high-frequency link to control power flow between batteries, load, and a renewable source such as...
متن کاملCell Balancing of a Multi-Cell Battery Storage System for Renewable Energy DC Micro-Grids
The paper analyzes different concepts for active charge balancing for a multi-cell battery energy storage system used as a backbone for a DC micro grid. The storage system is based on a cascaded multi-level converter topology where each (lead-acid) battery is equipped with dedicated low-voltage buck type DC/DC converter stage placed directly at the battery terminals. To minimize the output ripp...
متن کاملControl for Renewable Energy and Smart Grids
The use of renewable energy increased greatly just after the first big oil crisis in the late seventies. At that time, economic issues were the most important factors, hence interest in such processes decreased when oil prices fell. The current resurgence of interest in the use of renewable energy is driven by the need to reduce the high environmental impact of fossil-based energy systems. Harv...
متن کاملHigh-Efficiency Battery Storage Unit for Renewable Energy DC Micro-Grids
The paper describes a battery storage unit for small DC micro-grids based on a multi-cell topology. The system consists of a series arrangement of lead-acid type battery cells where each cell is equipped with an individual DC-DC buck converter located directly at the battery terminals. For minimizing the output ripple the cells are operated in interleaved PWM mode. With this the cell-to-cell wi...
متن کاملA bidirectional DC-DC converter for renewable energy systems
To improve the energy quality, most of the renewable energy systems include an energy storage element charged by the bidirectional DC-DC converter. This paper proposes the bidirectional DC-DC converter which employs the two bridge configuration resonant class-E converters on the both sides of the isolating transformer. The low side converter is controlled as step up and the high side converter ...
