In the Wind Power Market, Recentry for to improve for performance of Wind Turbine, Permanent Magnet Type Synchronous Generator is used in there, especially the fractional slot winding is extremely effective.
Recently, efficiency improvement has been noted with the rapidly increasing consumption of energy. The diode losses is the main cause of efficiency decrease in bridge rectifier of conventional PFC circuit, it can not be neglected. Therefore bridgeless PFC circuit has been focused. In this research, the various bridgeless PFC circuits are analyzed. The results of switching noise are compared and efficiency...
Telecommunication and data centers are moving to greener technology to minimize operating costs and lessen environmental impact. Ultimately, the networking and computing loads in these applications are DC rather than AC, and many renewable energy sources develop DC power as well. Energy storage systems are also DC, such as those required for Uninterruptable Power Supplies (UPS), as well as those needed...
In this paper, implementation results of two different topologies for a fuel cell-supercapacitor (SC) hybrid system are presented. In first topology, the SC bank is connected to a low voltage DC-bus while in the second one, it is connected to a high voltage DC-bus through a DC-DC converter. The energy management is carried out in both the topologies with the same control method based on notion of...
