Nonlinear modeling and optimization of reconfigurable GaN-HEMT oscillator–rectifier circuits for bidirectional wireless power transfer

id="offer-description" class="ecl-u-type-heading-2 ecl-u-mt-none ecl-u-mb-l">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
