“…(13) in which P core,v is the time-average power loss per unit volume and the parameters k, a, and b can be found in the datasheets [19]. However, the above equation is only valid for sinusoidal current waveforms, therefore in order to obtain a good estimation, as it is discussed in [16], the core losses P core is calculated following improved Generalized Steinmetz Equation (iGSE) [17],…”

Abstract-Electronic Inductor (EI) techniques are promising approaches for improving the grid-side current quality, and they are suitable for motor drive applications. In this paper, different EI topologies are investigated from the efficiency perspective, including the effect of employing Silicon Carbide (SiC) power devices. Moreover, the influence of partial loading on component sizing in Adjustable Speed Drives (ASDs) is studied. Finally the analytical loss modelling of power switches is utilized for efficiency measurement. The theoretical analyses are verified by experimental benchmarking in an ASD system.

This paper presents an optimal design procedure for pulse transformers fed by power converters for supplying pulsed current magnets in particle accelerators. Usually their volume must be minimized because of limited space available in the accelerator tunnel. Analytical and numerical models are presented as well as an experimental validation and a real case study where the design tool is exploited to derive a wide variety of solutions depending on the pulse transformers location with respect to the magnet position.

“…1(a,b), which makes the above methods not accurate and not suitable anymore. 1 Recent years, many other core loss calculation approaches based on SE have been developed for non-sinusoidal excitations, including the modified Steinmetz equation 5 and waveform coefficient Steinmetz equation (WcSE). 6 Each of these methods has its advantages and disadvantages, generally speaking, IGSE is considered as the best method in terms of accuracy and practical point of view, 7 which expression is given as follows:…”

Magnetic materials are widely used in switching-mode power supplies (SMPS) and magnetic components in SMPS usually work under two typical rectangular excitations (with or without the period of zero voltage). Extensive experimental results have shown that there is quite a difference of core loss between sinusoidal excitations and rectangular excitations, which means the traditional core loss calculation methods are no longer applicable. In this paper, two formulas for core loss calculation under the above rectangular excitations are derived based on the Improved Generalized Steinmetz Equation (IGSE). Core loss of different magnetic materials, under both sinusoidal excitations and rectangular excitations with different frequencies and duty cycles, are measured. Experimental results show that the formulas are accurate enough and very useful to predict the core loss.
