Doctoral student in Power Electronics, focusing on modular GaN power converters KTH Royal Institute of Technology in Sweden

This doctoral position at KTH Royal Institute of Technology focuses on power electronics, specifically the development of modular Gallium Nitride (GaN) power converters. GaN semiconductors are revolutionizing power electronics by enabling reduced losses and higher switching frequencies, and are already used in low-power applications. The research will center on integrating GaN devices into modular converter structures, aiming to create compact and highly efficient drive systems for high-power applications such as electric trucks and buses.

The successful candidate will join a dynamic research team at KTH, working on a broad range of power electronics topics including converter topologies, design, reliability, and control. The project is part of the large European research initiative Moore4Power, providing excellent opportunities for networking and collaboration across Europe.

Supervision will be provided by Dr. Staffan Norrga, an expert in the field. The position is based in Stockholm, Sweden, and offers a creative and supportive environment with attractive benefits. KTH is committed to equality, diversity, and sustainability, and provides a workplace with many employee benefits.

Funding is available through a monthly salary as per KTH’s doctoral student salary agreement. The employment is full-time and can last up to four years, with renewal options. Doctoral students may also engage in training and administrative tasks up to 20% of their time.

Eligibility requires a second cycle degree (such as a master's) or equivalent, or completion of at least 240 higher education credits (with at least 60 at second-cycle level). English proficiency equivalent to English B/6 is mandatory. Selection emphasizes personal skills, including independence, collaboration, professionalism, and analytical ability. Applications must include certified copies of diplomas and grades, proof of language proficiency, CV, application letter (max 2 pages), and representative publications or technical reports (with summaries and web links if lengthy).

Applications are to be submitted via KTH’s recruitment system by 2026-05-31. The position may require security clearance if classified as security-sensitive. For further information, refer to the official job advertisement and KTH’s doctoral studies resources.

This is an excellent opportunity to contribute to cutting-edge research in power electronics and to advance the transition towards sustainable, high-efficiency electric drive systems.
