Offer Description The BiWPT Doctoral Network on Bidirectional Wireless Power Transfer for Next-Generation Electric Mobility has a clear mission: to train a new generation of experts who possess the skills and fundamental knowledge required to effectively address the challenges of bidirectional WPT systems for electric mobility, enabling vehicle-grid integration in support of Europe’s energy transition. The network will advance fundamental understanding and practical implementation of efficient, compact, and misalignment-tolerant bidirectional WPT technologies. Expected innovations include novel electromagnetic coupling and converter designs, integrated shielding concepts and real-world demonstrators that enable seamless, efficient, and high-power electric vehicle charging and discharging. The network delivers a training programme to 15 Doctoral Candidates (DC), providing capabilities to become leaders of tomorrow’s R&I; in Europe.
Objective of the doctoral position : Design of reconfigurable GaN-HEMT-based circuits for bidirectional wireless power transfer (WPT)
systems, exploiting the time-reversal duality between oscillators and synchronous rectifiers to achieve comparable efficiency in power generation and rectification modes. The DC will target MHz-range operation and will include the development of accurate empirical models for nonlinear FET-like devices, with particular focus on third-quadrant I–V characterization to predict operation under negative drain–source voltages. Analytical and nonlinear CAD-based design methodologies for bidirectional WPT systems will be developed, followed by the implementation and experimental validation of the most promising circuit topologies, assessing key performance metrics such as conversion efficiency in both operating regimes.
The DC will participate in two planned secondments as part of the doctoral training programme: an academic secondment at the co-supervising university abroad and an industrial secondment at the mentor’s company. The DC is expected to submit regular progress reports to the local and network supervisors. In addition, the DC will actively participate in BiWPT’s training, dissemination, communication, and exploitation activities. The DC will prepare a doctoral thesis and publish scientific articles related to the research project.
