Résumé du contexte et des objectifs généraux du projet

This Doctoral Network (DN) implements a multidisciplinary, innovative research and training programme bringing together different scientific fields and industrial participation to enable a new generation of Doctoral Candidates (DCs) to investigate and develop electric drives in the context of electrification in the transition towards zero-emissions. Electrification is one of the key assets in green transition and future sustainable world.
While electrification offers one of the main solutions in reaching carbon-neutral societies, there is already now a lack of skilled persons in the field. Therefore, there is an urgent need to educate young highly skilled engineers with a breadth of interdisciplinarity on designing propulsion machines and power converters to become EU’s future leaders in power electronic systems (applied in renewable energy systems and electric vehicles - EVs). The proposed network is timely in meeting the challenges, bringing together the leading experts and providing best training opportunities to doctoral candidates (DC). This will make a step change in the EU’s key industry with potential impacts on other applications such as high-speed trains, electric vehicles, electric aircrafts and ships.
Electrification of transportation (road, aviation, train, maritime) in modern society is of critical importance in reducing greenhouse gas emissions. Transport needs to cut emissions by 90% by 2050. Thereby, electrification establishes an Innovation Union in the EU for smart, sustainable, and inclusive growth. High-speed technology enables high material and energy efficiency. Therefore, HIPO (integrated HIgh-speed POwer systems for industry and mobile applications) research and training programme will focus on providing Doctoral Candidates (DCs) with relevant knowledge, methods and skills across a wide range of disciplines around Electric High-Speed Drives. The unique structural innovation is to combine the design principles of thermal, electrical and mechanical sciences and to have engineering knowledge and modelling skills to design the energy supply unit taking into account in which machine it is connected. And vice versa, machine design experts shall learn to design machines in interaction with suppling power electronic control systems. This goal will be achieved by a unique combination of scientific research training, industrial internships and courses and seminars/workshops on scientific and complementary so-called “transferrable” or “soft” skills facilitated by a multidisciplinary, multisectoral and international consortium.

Travail effectué depuis le début du projet jusqu’à la fin de la période considérée dans le rapport et principaux résultats atteints jusqu’à présent

A new structure for a synchronous reluctance machine (SynRM) featuring a bridgeless rotor has been developed to enhance high-power and high-speed performance. This innovative approach eliminates performance-deteriorating bridges, improving electromagnetic performance by enhancing saliency and dq axis inductance. A comprehensive optimization method has been implemented to demonstrate the capabilities of the proposed bridgeless rotor SynRM (BLRSynRM).
Multi-physic model has been utilised for designing an axial flux machine for a truck application.
The selection of materials for the axially laminated (ALA) rotor of the synchronous reluctance motor has been completed. A comparative analysis was conducted to evaluate the mechanical, thermal, and magnetic properties of the available soft magnetic materials.
As an environmentally friendly and sustainable machine, electrically excited synchronous machine (EESM) has become a new alternative option to permanent magnet synchronous machine (PMSM). To achieve high-power and high-performance, an EESM design for high-speed vehicles has been developed.
A systematic time-frequency domain analytical and numerical EMI model of dc-fed voltage source inverters have been proposed and developedIn this approach, the switching function is modelled in the time domain, while the propagation path is modelled in the frequency domain. Common-mode (CM) and differential-mode (DM) noise sources are estimated, and the post-processing of this noise is performed in the frequency domain to estimate CM and DM emissions from the system. The developed model can predict emissions for different modulation techniques and dead times and is validated using PLECS simulation software.
The main impact is the reduction of simulation time with a factor of 1000 with the proposed hybrid time-frequency method comparing to the commercialized modelling software. This can enable possibility of finding the most optimum solution by investigate many different configurations in just one day.
