Analytical, FEM and Experimental Study of the Influence of the Airgap Size in Different Types of Ferrite Cores
(IEEE, 2022)
This work reviews and compares different airgap reluctance calculation approaches with experimental results, focusing on the Schwarz-Christoffel transformation. The modelling of the airgap reluctance in two dimensions is ...
Single Core and Modular Transformer Solutions: a Trade-Off Analysis of Volume, Losses and Temperature Rise
(IEEE, 2022)
In this paper, a comparison between single core and modular transformer solutions is made. Basic dimensional relations between volumes, areas and lengths are used to obtain mathematical expression of the power losses and ...
Dynamic Wireless Power Transfer DWPT Time Domain model: xyz position and speed coupling effect
(IEEE, 2022)
The paper presents a DWPT system time domain model which considers speed and position (x, y, z) coupling effects. The speed effect compared to static WPT, presents an active behavior that should be considered during the ...
Benefits of switching from Si to SiC modules with further converter optimization
(IEEE, 2022)
SiC semiconductors have better characteristics than Si, improving power electronics converters performances. A prototype that can switch semiconductor technology without changing any other part of the system is built and ...
