jobbeskrivelse:

The Electronics group (ELE) at DTU Elektro seeks a qualified candidate for a vacant 3-year PhD position in the area of power electronics.

DTU ELE group is responsible for power electronics research including advanced high efficiency dc-dc and dc-ac converters for renewable energy and storage applications. The goal of this PhD project is to research 1-10kW highly efficient and bidirectional ac-dc converter based on partial power regulation concept.

Responsibilities and tasks

Efficient and effective energy systems integration with renewable and clean energies has been very critical for the future fossil-free society. Power-to-X (P2X) is a promising option for storing intermittent renewables and providing clean energy to residential, industrial, transportation users. In such systems, high efficiency and low cost, which are always the two conflict parameters for a power electronics system, must be satisfied at the same time for P2X applications. Therefore, a multidisciplinary study needs to be carried out by researchers from the scientific fields e.g. electrical engineering, electrochemical, material science and thermal engineering, and the challenges have not yet been solved completely due to the system complexity. This PhD project will focus on the partial power regulation based new power electronic topology and configuration, in particular, ac-dc rectifiers for both cost reduction and efficiency improvement. Appling modular design concept, a 10-kW ac-dc high-frequency-link converter will be developed and optimized as a hardware platform, on which advanced control strategies will be researched to achieve fraction power processing and reactive power compensation.

This PhD project is granted by Innovation Fund Denmark (IFD) and will carry out with close collaboration of Danish and international industrial partners.

Any candidate who:

• is familiar with energy storage systems, such as batteries and electrolysis
• is familiar with active filtering and power factor correction techniques
• has good grasps of analysis and synthesis of both hard-switched and soft-switched ac-dc and dc-dc converters
• has experience on AC-DC or DC-AC converter analysis and design
• has experience with digital control and programming digital signal processer (DSP)
• has good experience in using PCB layout software
• has good experience in making laboratory prototypes, debugging and testing power electronic circuits
• is able to use communication skill in English at a good level

will be considered as a candidate with favorable background. The candidate with highly self-motivation and enthusiasm, and is able to work well in a team environment.

Qualifications

Candidates should have a master's degree in engineering or a similar degree with an academic level equivalent to the master's degree in engineering.

Approval and Enrolment

The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU.
