Objectives
Resonant power converters rely on precise leakage inductance values to achieve soft-switching, minimise losses, and maintain operational stability. The proliferation of SiC and GaN devices, which generate high-frequency harmonics, makes accurate leakage estimation increasingly challenging. Traditional analytical or 2D simulation methods often fail to account for strand-level variations, winding layout effects, or non-uniform current distributions, resulting in design margins that limit efficiency and power density.
Advanced 3D electromagnetic modelling, coupled with stochastic analysis of winding arrangements and multi-objective optimisation, allows designers to predict leakage inductance with unprecedented accuracy. By combining high-fidelity simulation with MAGNIFY’s core loss models for novel magnetic materials, this project develops tools and workflows that optimise magnetic geometry, winding layout, and material choice for resonant converters, ensuring maximum efficiency and reliability in high-frequency, high-power applications.
Objectives 1
Measure the leakage inductance and power losses of conventional magnetic devices with different materials.
Objectives 2
Study the impact of the harmonics from WBG devices (SiC, GaN) on magnetic components, with focus on the leakage inductance.
Objectives 3
Use existing and MAGNIFY’s core loss models for novel magnetic materials in magnetic devices for resonant converters.
Objectives 4
Stochastic study of influence the individual strand positions on the inductance.
Objectives 5
3-D geometry, shape and size multi-objective optimisation of magnetic components for accurate estimation of leakage inductance and efficiency maximisation.
Objectives 6
Validation in actual resonant converters with WBG semiconductors.
