Objectives
Accurate magnetic component design is essential for modern power electronics, especially as converters operate under increasingly dynamic and non-sinusoidal conditions. Traditional frequency-domain loss models, while useful, often fail to capture the nonlinear and time-dependent behaviour of magnetic materials subjected to realistic switching waveforms. Dynamic hysteresis models (DHMs) offer a powerful alternative by enabling time-domain simulation of magnetisation processes and losses, thereby improving predictive accuracy for applications such as LCL filters and boost inductors.
This project builds a comprehensive design workflow that integrates advanced hysteresis modelling, material characterisation, and time-domain simulation tools. Through a combination of experimental measurements, modelling, and practical validation, the work aims to enable accurate, high-efficiency inductor design suitable for industrial converter applications.
Objectives 1
Measurement of magnetisation curves and losses from different materials: laminations, SMCs (from UPJS) and ferrites (from CERTH).
Objectives 2
Identification of phenomenological dynamic hysteresis models (DHMs)67 for the aforementioned materials based on the measurements.
Objectives 3
Implementation of the DHMs in MATLAB/Simulink environment. and coupling to Simscape blocks for accounting for converter supply.
Objectives 4
Design and optimisation of single-phase LCL filter inductors using the Simulink tools: Parametrising the inductor with respect to turn number N, cross-sectional area AFe, magnetic path length lFe and air-gap length δ. Finding optimal N, AFe, lFe and δ for a filter inductor and a boost inductor, so that current ripple limits are met and a pareto-optimum for efficiency/power density is found.
Objectives 5
Validation measurements in an industrial converter application.
