Job description

Worldwide, we consume vast amounts of electricity, with data centers and compute currently accounting for more than 2% of global consumption. This share is growing exponentially year-over-year. Within a decade, compute could consume as much as 10%. Are you on board with us to embrace the challenge of designing next-generation power transformers for AI data centers? Are you our next PhD candidate to work on enablers of future compute - the high-frequency transformers?

Information

The EPE group at TU/e seeks a motivated PhD researcher to advance the state-of-the-art in power electronics transformers (PETs) for data center applications. This position offers a unique opportunity to work at the intersection of high-voltage engineering, high-frequency transformer, and AI-driven design optimization, with direct industrial collaboration and real-world impact on the sustainability of AI infrastructure.

You will enroll as a PhD candidate in the group of Electromechanics and Power Electronics (EPE) at TU/e, in close collaboration with Delta Energy System GmbH, a leading industrial partner in power electronics for data centers.

Your research will be concerned with developing high-frequency, medium-voltage transformer architectures supported by partial discharge (PD) modeling methodologies that enable >99.5% efficiency, >10kV operation, and tens fold copper reduction compared to conventional designs. Your research will directly address the power density and efficiency challenges faced by modern data centers powering AI and machine learning workloads.

You will aim at advancing the state-of-the-art in solid state transformers for data center applications. This includes designing high-frequency transformer architectures with novel insulation concepts, prone to high voltage stresses and endure the accelerated ageing through developing predictive models for partial discharge behavior, and validating designs through simulation and experimental testing. The goal is to create transformers that achieve unprecedented efficiency, power density, and reliability for AI infrastructure.

You will have access to state-of-the-art simulation tools (ANSYS Maxwell, COMSOL) and high-voltage testing facilities. Research results will contribute to making AI data centers more sustainable by dramatically improving the efficiency and power density of their power delivery systems. With data center energy consumption growing exponentially due to AI/ML workloads, your research has direct impact on reducing the carbon footprint of digital infrastructure.

Requirements

• A master's degree (or equivalent university degree) in Electrical Engineering, Electromechanics, Power Electronics, High-Voltage Engineering, or a related field
• A research-oriented attitude with strong analytical and problem-solving skills
• Ability, with demonstrated experience, to work in an interdisciplinary team and interest in collaborating with industrial partners and other stakeholders
• Motivated to develop your teaching skills and coach students
• Fluent in spoken and written English (C1 level or equivalent)
• Based on our candidate assessment, the following skills are valuable:
  • Required:
    • Demonstrated knowledge in the physics of transformers, magnetism. Familiarity with numerical tools (ANSYS Maxwell, COMSOL, or similar). Knowledge of mathematics behind Finite Element Method, and manipulation of custom numerical toolboxes is a strong asset
    • Affinity with high-voltage engineering, fundamentals and insulation system understanding.
    • Understanding of power electronics and transformer design principles
  • Advantageous:
    • Experience with partial discharge phenomena and measurement equipment, and other PD peculiarities.
    • Knowledge of basic ML methods and accompanying tools such as (Python, TensorFlow, PyTorch) for predictive modeling.
    • Familiarity with multiphysics strong and/or weak coupling.
    • Hands-on experimental validation experience in high-voltage laboratories.
