Magnetic Field Conforming Multiscale Formulations for Locally-Confined Nonlinear Eddy Current Problems Using the FE-HMM Method
Innocent Niyonzima, Gérard Meunier, Antoine Marteau +4
Magnetic composites used for the conversion of electrical energy often incorporate ferromagnetic inclusions insulated from each other to mitigate eddy current losses. Numerical mod…
Hyperbolic Basis Functions for Time-Transient Analysis of Eddy Currents in Conductive and Magnetic Thin Sheets
Bruno de Sousa Alves, Ruth V. Sabariego, Marc Laforest +1
This paper presents a new time-domain finite-element approach for modelling thin sheets with hyperbolic basis functions derived from the well-known steady-state solution of the lin…
Efficient simulation of DC-AC power converters using Multirate Partial Differential Equations
Andreas Pels, Ruth V. Sabariego, Sebastian Schöps
Switch-mode power converters are used in various applications to convert between different voltage (or current) levels. They use transistors to switch on and off the input voltage…
Multirate PWM balance method for the efficient field-circuit coupled simulation of power converters
Andreas Pels, Herbert De Gersem, Ruth V. Sabariego +1
The field-circuit coupled simulation of switch-mode power converters with conventional time discretization is computationally expensive since very small time steps are needed to ap…
POD-based reduced-order model of an eddy-current levitation problem
MD Rokibul Hasan, Laurent Montier, Thomas Henneron +1
The accurate and efficient treatment of eddy-current problems with movement is still a challenge. Very few works applying reduced-order models are available in the literature. In t…
