Objectives
Rapid electrification of heavy transport, industrial processes, and large-scale energy systems is driving the adoption of multi-megawatt (MW) power converters. These converters operate at increasingly high switching frequencies enabled by wide-bandgap (WBG) technologies such as SiC, enabling substantial improvements in efficiency and system compactness. However, high-frequency switching also generates strong electromagnetic interference (EMI), harmonic distortion, and common-mode (CM) and differential-mode (DM) noise, placing extreme demands on filtering solutions.
Traditional filters—often bulky, discrete, and lossy—are no longer sufficient. To meet emerging industry requirements, filters must become integrated, meaning that magnetic components, parasitics, and structural elements work together rather than against each other. This project tackles the challenge by developing integrated filter topologies and magnetic designs capable of operating efficiently in multi-MW, high-frequency environments while meeting cost, manufacturability, and EMI constraints.
Objectives 1
Develop models for integrated filter topologies suited for three-phase converters focusing on common and differential mode filtering, and effectively using parasitic components (resistance and capacitance) for better filtering.
Objectives 2
Create novel magnetic arrangements with multi-phase matrix-inductors and new winding designs for next-generation power converters.
Objectives 3
Optimise filter inductor designs for technical performance (efficiency, power density, parasitic and HF effects) and commercial viability (cost, manufacturability, emission standards).
Objectives 4
Validate new designs through laboratory prototypes in conjunction with multi-megawatt power converters.
