Title of Research Activity: Innovative Design and Performance Prediction of Traction E-Machine for Motorsport Application
Brief description of research activity: Alongside the road electric vehicles increasing in popularity, several challenging applications such as motorsport fully electric competitions are being born. Within the development of innovative powertrains, the electric motor has a leading rule. It needs to deliver high performance, be efficient and operate over dynamic drive cycles in which deliver peak performances for short time. High torque and low weight are the main requirements which translates into high torque per weight ratio. An innovative high-performance brushless permanent magnet (BPM) machine has been designed. In order to design the performing machine, several models and equations have been introduced with the aim of including 3D effects and high frequency losses. These new models have assisted with the machine performance prediction over single operating points and real racing cycles. It has been possible, therefore, to consider the machine behavior during a race and different circuits can be analyzed.

Title of Research Activity: Large-bandwidth triple-loop control of the grid-connected inverter
Brief description of research activity: In the on-going process of renovation of the electrical energy distribution networks, new paradigms are emerging, for both the three-phase, high- and medium-voltage infrastructure and the single-phase, low-voltage utility grid organization. Referring to the latter, the nano- or micro-grid is attracting considerable interest. Where, applicable standards pose power quality and grid support function requirements for converters that interface energy resources of dc nature with the ac utility grid. At the same time, additional functionalities are also expected, enabling the effective integration of hybrid (i.e., dc or ac) micro-grids, able to operate both grid-connected and islanded. To this purpose, a novel controller organization is proposed, which is referred to as large-bandwidth triple-loop control. It allows interfacing renewable sources and loads, aggregated in dc and ac nano- or micro-grids, with smart power systems, providing enhanced power quality, stability and flexibility of operation.

Title of Research Activity: Design and characterization of high-power (S>250kVA) SiC-based current source inverter for photovoltaic applications
Brief description of research activity: Classically, the power conversion systems in photovoltaic (PV) domain are muti-stage voltage-based structures, which have some specific drawbacks as short lifetime and relatively reduced efficiency. In order to overcome these disadvantages, the Current Source Inverter (CSI) topology can be employed. The CSI could replace both stages of the classic PV inverter and it would allow the utilization of a 690V/20kV step-up transformer, focusing on a more efficient and standardized conversion system. Furthermore, recent improvements in semiconductors field allow the utilization of 1,7kV Silicon Carbide (SiC) devices, which feature outstanding on-state and switching performances. The main objective of this PhD thesis is to conceive and characterize a SiC-based Current Source Inverter suitable for photovoltaic applications.

Egi Nazeraj received his B.Sc. in Power Engineering from the University of Rome “La Sapienza” and M.Sc. in Electromechanical Engineering in the frame of the BRUFACE program (VUB-ULB). His Bachelor’s thesis was done at A.S.M. Terni, a DSO in Italy, where he developed an algorithm to predict the load diagrams based on information from smart meters. His master’s thesis was done at Siemens Industry Software within European project (ARMEVA) for developing advanced reluctance motors for vehicles applications. His contribution was to create a new methodology for studying Noise, Vibration and Harshness of a reluctance motor during a transient run up. He was part of volunteering associations as Engineering without Borders Italy and Humasol, where he designed PV stand-alone systems and solar pumping systems in Madagascar and Uganda respectively. He is currently a Ph.D. researcher in the Department of Electrical Engineering and Energy Technology (ETEC) at Vrije Universiteit Brussel (VUB) and at the Mobility, Logistics and Automotive Technology Research Centre (MOBI). His research is focused on design, control and optimization of Multiport DC/DC Converters for hybrid applications.

TITLE OF RESEARCH ACTIVITY:
Optimal Design and Energy Management Control of Multiport DC/DC Converters for Hybrid Systems.
BRIEF DESCRIPTION OF RESEARCH ACTIVITY:
Nowadays hybrid systems are becoming popular thanks to the advantages of combining multiple sources. However, each source requires its own power electronic converter to be integrated in the system. Multiport DC/DC converters are able to manage the power flow of multiple DC sources with the advantage of higher efficiency when compared to single port converters. The research is focused on the design optimization and energy management control of the Multiport DC/DC. Special attentions are given to the trade-off between interleaved technique and SiC technology and to the optimal thermal management.
