The Power Electronics and Electromagnetic Compatibility Group within the department Electrical Engineering has a vacancy for a Ph.D. researcher to work on EASIER - Electric Aircraft System Integration Enabler. The objective of the project is to investigate challenges presented by aircraft electric propulsion requires the development of new airborne technologies that enable expanding the electrification technology trend already impacting other areas, like ground transportation or the autonomous generation/usage of electricity from renewables, to efficient and economical air transportation. The project is funded by the European Commission under the Horizon 2020 Program. Within the project, a strong partnership is established among all members of the EASIER consortium from EU and US who will collaborate following a coordinated plan, with the Industrial Advisory Board: Partners:

Electromagnetic Compatibility, the UT researcher will participate in the following tasks:
Modelling of power systems 
Provide measurement and code-to-code based validations that will be used by NLR to validate and tune the developed models 

Modelling of miniaturized filters 
Create models of nano-crystalline-chokes that can be used in the design of miniaturized filters. The materials used in these chokes ensure a major decrease in volume and weight. Other promising magnetic components may also be evaluated.  Utilize full-wave 3D modelling together with back-annotating field effects in circuit simulations to ensure performance while reducing complexity. Perform validations and tuning of the created model based on measurements and code-to-code validation. 

Power quality modelling
Create behavioural models of loads that will be integrated into a larger system. 

Analysis and mitigation of conducted and radiated EMI 
Select representative subsets of the aircraft electric propulsion system such as the motor drive and motor for propulsion, and the battery interface to the aircraft electrical network, and study them in detail. 
Evaluate conducted and radiated EMI on the aircraft electric distribution, targeting input and output filter requirements, shielding of boxes and cabinets, and “silent” power semiconductor device switching behaviour. Design, develop and test EMI mitigation solutions at the interface between the propulsion and the power distribution sections. Predicted solutions consist of active filtering techniques in combination with passive filters, interface connections, shielding of critical noise sources and detuning resonances.

We are looking for a highly motivated, enthusiastic and curiosity-driven researcher;

• You have, or are about to get, a master’s degree in power electronics, packaging, electromagnetics, material science or a related field;
• You have a background in physical electronics, analytical mathematics and simulation;
• You are familiar with numerical methods in mathematics and physics, such as finite difference and finite element methods;
• You are an excellent teammate in an enthusiastic and hardworking group of scientists and engineers working on a joint assignment;
• You are creative, like to push boundaries, and are highly motivated to address major science challenges in light-matter interaction physics;
• You are proficient in English and able to collaborate intensively with industrial and academic parties in regular meetings and work visits.

The University of Twente. We stand for life sciences and technology. High tech and human touch. Education and research that matter. New technology which leads change, innovation and progress in society. The University of Twente is the only campus university of the Netherlands; divided over five faculties we provide more than fifty educational programmes. We have a strong focus on personal development and talented researchers are given scope for carrying out groundbreaking research.

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status or disability status. Because of our diversity values we do particularly support women to apply.

The faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) comprises three disciplines that shape Information and Communication Technology. ICT is more than communication. In almost every product we use mathematics, electronics and computer technology and ICT now contributes to all of societies' activities. The faculty works together intensively with industrial partners and researchers in the Netherlands and abroad and conducts extensive research for external commissioning parties and funders. The research which enjoys a high profile both at home and internationally, has been accommodated in the multidisciplinary research institutes: Mesa+ Institute, TechMed Centra and Digital Society Institute.
