PhD on Highly Robust High-Power AC-DC Converter for Green Hydrogen Production

Green hydrogen has a central role in enabling the global energy transition, and the technologies related to it must develop quickly according to new market needs. One of these technologies is the AC–DC power electronics used to provide DC power to the electrolysis system. Even though the rectifier is a well-established system in high-power applications, the state-of-the-art technology is based on IGBT semiconductors with limited switching frequency. The new wideband gap semiconductors, like the Silicon Carbide (SiC) MOSFETs, allow the rectifier to operate at higher frequencies, resulting in highly efficient and smaller systems (reduced footprint). Nevertheless, the higher operation of such devices poses new challenges in terms of protection, which are still unsolved. Unlike IGBT, wideband gap devices cannot withstand short-circuit currents for enough time until the actuation of the protection. Therefore, new protection schemes must be proposed in order to make the wideband gap-based rectifier robust enough for industry standards.

To address these challenges, we are looking for a motivated PhD candidate interested in working on advanced protection strategies for active front-end rectifier and innovative fault-tolerant topologies.

Information
The PhD will be part of the IMPROvE project: Industrial monitoring and protection with power microelectronics. The project aims to develop a highly robust rectifier for electrolysis applications, with a focus on advanced protection strategies and innovative fault-tolerant circuit topologies. The research will address faults from the component level to the system level. Initially, fault detection techniques at the semiconductor level will be explored, particularly for wide bandgap devices, leading to the development of a comprehensive fault identification and isolation scheme. In parallel, new power electronic topologies will be investigated to propose a novel fault-tolerant rectifier design. At the system level, the project will also explore fault detection and isolation in parallel power electronics systems. Besides, the proposed solution should be implemented and validated experimentally in order to demonstrate the effectiveness of the proposed protection schemes and rectifier topologies under realistic fault scenarios.

Besides research, you will also contribute to education within the department. Apart from supervising BSc and MSc students in their research projects, other assistance in education, e.g. in bachelor courses, is also expected. The overall load usually amounts to around 10% of your contract time.

The mission of the Department of Electrical Engineering is to acquire, share and transfer knowledge and understanding in the whole field of Electrical Engineering through education, research and valorization. We work towards a ‘Smart Sustainable Society’, a ‘Connected World’, and a healthy humanity (‘Care & Cure’). Activities share an application-oriented character, a high degree of complexity and a large synergy between multiple facets of the field.

Research is carried out into the applications of electromagnetic phenomena in all forms of energy conversion, telecommunication and electrical signal processing. Existing and new electrical components and systems are analyzed, designed and built. The Electrical Engineering department takes its inspiration from contacts with high-tech industry in the direct surrounding region and beyond.

The department is innovative and has international ambitions and partnerships. The result is a challenging and inspiring setting in which socially relevant issues are addressed.
