   Analysis and Modelling of a Permanent Magnet Biased Inductor Used in Motor Drive Systems
By Marco ZUCCHERATO [View]
[Download]

Abstract: In this paper, a permanent magnet biased inductor has been analysed and designed for a frequency converter. Line current harmonic and conducted emission tests have been carried out to compare the performance of the hybrid inductor. The analysis shows that the hybrid inductor can have volume reduction in comparison with a traditional inductor.

   Impact of Core Shape and Material on the Acoustic Noise Emission of Medium Frequency, Medium Voltage Transformers
By Peng SHUAI [View]
[Download]

Abstract: Acoustic noise emission of transformers is mainly due to core vibration induced by reluctance force and magnetostriction which is highly dependent on the core material and geometry. This paper investigates the vibration and acoustic noise of nanocrystalline cores with different geometric shapes based on FEM simulation and experimental measurements. Furthermore, the optimal design of medium frequency transformers (MFT) by using different core materials and geometric shapes is analyzed to find the most suitable core for MFT design with high efficiency, high power density and low acoustic noise emission.

   Optimal Cross Section Shape of Tape Wound Cores
By Bernardo COUGO [View]
[Download]

Abstract: Tape wound cores are used in different applications where high power density is desired due to their high performance at high frequencies. In high power applications, inductor and transformer cores have large cross sections and consequently wide core legs which may result in different flux densities and temperatures in each layer as experimentally shown. This paper verifies the influence of the core cross section shape in the losses and temperature distribution inside the core. Optimal cross section shapes are developed in order to minimize different criteria such as core losses, heat extraction capabilities and total core weight.

   Optimized Filter Inductors for a 1MW Windmill Demonstrator with an Objective to Reduced Converter Size
By Alexander STADLER [View]
[Download]

Abstract: In this paper, thermally optimized filter inductors are presented for a 1MW windmill demonstrator. It is shown how simulation based on finite element method (FEM) can be used to predict the L(I) inductance curve, the core losses and the hot-spot temperature as well. Extensive measurements are conducted to verify all simulated data. To draw a conclusion, inductors based on different core materials are compared against each other.
