   Analysis Of Inductance And Magnetic Field Distribution In The Superconducting Coil Assigned For Energy Storage Applications
By T. Biskup, C. Buehrer, B. Grzesik, J. Krijgsman, J. Michalak, S. Pasko, M. Stepien, M. A. Zygmanowski [View]

Abstract: The paper describes analysis of high temperature superconducting (HTS) coil properties. The aim of analysis is design of coil with maximum inductance at given coil wire length. Also distribution of magnetic field is important because superconducting phenomena exist only below allowable flux density and it depends on direction of magnetic flux. The paper is looking for coil toroidal in shape with circular cross-section area of coil. The coil with ferromagnetic core is taken into account. Windings of the coil are made from rectangular superconducting wire. The cross-section of the wire is 2.5 mm2 and total length about 300 m. The whole analysis is carried out using ANSYS software based of Finite Elements Method. Inductance of coil and stored energy are calculated at assumption of 100 Aof direct current per wire.

   Approaches To Building Single-Stage Ac/ac Conversion Switch-Mode Audio Power Amplifiers
By Petar Ljusev, Michael A. E. Andersen [View]

Abstract: This paper discusses the possible topologies and promising approaches towards direct single-phase AC-AC conversion of the mains voltage for audio applications. When compared to standard Class-D switching audio power ampliers with a separate power supply, it is expected that direct conversion will provide better efciency and higher level of integration, leading to lower component count, volume and cost, but at the expense of a minor performance deterioration.

Abstract: Electrical networks with much small unstable power sources and stability problems in such networks are considered. Such networks arise after more implementing “green”, renewable energy sources in traditionally electrical networks.

   Tracking Power Supply For Automotive Multi-Channel Single-Ended Pwm Audio Amplifier System
By Mikkel C. W. Hoyerby, Dennis R. Andersen, Michael A. E. Andersen [View]
[Download]

Abstract: This paper presents the derivation of a practical design solution for a tracking power supply for single-ended switching audio amplifiers, motivated by requirements for reduced EMI. The selection and optimization of a suitable power conversion topology capable of handling ‘supply pumping’ caused by single-ended switching amplifiers is emphasized, and the results obtained from the constructed pro totype power supply are presented.
