Abstract :

The growing interest in high-frequency power conversion has driven significant research into resonant topologies operating in the multi-MHz range. While these converters offer compelling benefits in terms of size reduction, efficiency, and dynamic performance, their design presents unique challenges that extend beyond traditional power electronics paradigms.
This thesis investigates the conceptual, methodological, and practical aspects of designing multi-MHz resonant converters. It focuses on the development and application of dedicated tools and design methodologies suited to this frequency domain. A comprehensive framework is proposed to support the design process, from early conceptual modeling to detailed implementation.
The work adopts an exploratory approach and incorporates a historical perspective to contextualize the proposed methodologies within the broader evolution of resonant converter research. The result is a set of insights and analytical methods aimed at supporting the design of next-generation resonant converters in the multi-MHz regime.
