American Institute of Physics2016Leakage Flux Modelling of Multi-Winding Transformer using Permeance Magnetic Circuit
Drazen Dujic, Min Luo, Jost Allmeling
The size and position difference of the windings determine the leakage flux path and give rise to unbalance of the short-circuit impedances, which strongly affects the transient behaviour of the transformer. This work proposes a new approach of modelling w ...
Ieee2016Magnetic microrobots with addressable shape control
Shape shifting soft microrobots are generated from self-folding hydrogel bilayer structures. The folding conditions are analyzed to develop an optimal strategy for producing desired three-dimensional shapes. We present two different methods for programming ...
IEEE2016Functionally graded polymer nanocomposites using magnetic fields
Functionally Graded Materials (FGM) are a class of materials in which the composition and the properties gradually change over the volume. The present PhD project aims to generate a full understanding of a novel synthetic strategy for polymeric FGMs based ...
