   Applicability of an Open- and Balance-Type Calorimeter to VSC Loss Measurement
By Lassi AARNIOVUORI, Antti KOSONEN, Markku NIEMELÄ, Juha PYRHÖNEN [View]
[Download]

Abstract: The applicability of open- and balance-type calorimeter in energy efficiency level classifications offrequency converters is studied and compared with an input-output method carried out by a power analyser.The effect of heat source location and the frequency converter ventilation fan is tested and analysed

   EMI filter design methodology taking into account the static converter impedance
By Carlos CUELLAR, Nadir IDIR [View]
[Download]

Abstract: The classic procedure design of EMI filters determines the insertion loss of the common mode anddifferential mode filters under standardized 50#937; at the input and output impedances. In order to choosethe more adapted filter topology for a static converter, its necessary to consider the exact impedancesconnected to the input and output port in operating conditions. These impedances represent the LISNand the static converter which are measured with the current injection method. For simulation purpose,equivalent electrical circuit models are obtained and then applied in the filter design process.

   Magnitude Oriented Intelligent Grouping Scheme for Harmonics Above 2 kHz
By Tomas BEDRNIK, Leos KUKACKA, Jan KRAUS [View]
[Download]

Abstract: The article touches the topic of processing the measurements of high frequency harmonics in power grids (above 2 kHz). Measurements in wider band do produce large volumes of data. But often not all of these need to be stored in their raw form for further analysis. This article discusses some adaptable possibilities of reducing the amount of data and proposes an intelligent magnitude-oriented scheme of grouping harmonics instead of the one defined in current standards.

   The Overview of Damping Methods for Three-phase Grid-tired Inverter with LLCL-filter
By Min HUANG, POH CHIANG LOH, FREDE BLAABJERG [View]
[Download]

Abstract: Compared with LCL filter, an LLCL-filter is characterized with smaller size and lower cost for grid-connected inverters. But this high order filter may also have resonant problem which will affect the system stability. Many methods can be used to alleviate the resonant problem including active damping, passive damping or even without damping if it is designed conservative. In this paper, an overview of damping methods for three-phase voltage-source grid-tied with LLCL-filter is given. This paper also analyzes damping principle of each method including passive damping and active damping and shows the advantages as well as disadvantages of these methods.
