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...
Decarbonisation policies adopted worldwide are leading to an increasing deployment of renewable energy sources. In Europe, the growing number of offshore wind farm projects calls for scrutinising merits and opportunities of their interconnection via multi-terminal links rather than conventional point-to-point connections. The semiconductor components used in the converters and the resistance of power...
In tandem with the penetration of PHV as well as EV, contact-less power supply system in parking towers have become important subjects. In parking towers, EV and PHV are charged on the traveling pallets, supply power is to be transmitted from the building to travelling pallets. In this paper, high-frequency link AC-AC converter for contact-less power supply system in parking tower is newly proposed...
This paper proposes a power conversion circuit for the high-brightness white LED lamp powered by the solar-cell panel with a subsidiary battery set. The system operation is illustrated by five states according to the power flowing among the solar panel, the battery set, and the LED lamp under different sunlight intensities. A laboratory circuit designed for an 18 W LED lamp is built and tested to...
This paper presents a single phase inverter for the use of transformer-linked interleaved flyback converter. Compared with the core size of conventional type and proposed type flyback converter, the compact and light weight performance of the core are realizable. The power conversion system to propose comprises a flyback converter and a single phase inverter. Since the smoothing capacitor between...
