Abstract: In wireless power transfer (WPT) systems, as in many power electronics applications, the goal is to deliver more power efficiently within a compact form factor. Achieving this requires breakthroughs in two key areas: power converters (inverters and rectifiers) and WPT couplers. While modularity has been widely adopted in high-power systems, integration has typically been applied to high-speed, high-frequency, but lower-power designs. For high-frequency, high-power WPT, combining modularity and integration offers the best potential for advancing performance and power density.
This presentation will introduce the concept, in-depth analysis, and design of a poly-phase coupler, which integrates multiple modular coils within the same physical area to enable a highly compact, high-power WPT system. We will then explore a wide-bandgap-based, integrated modular power electronics approach that interfaces seamlessly with the integrated coupler, aiming to achieve reliable, efficient, and low-noise high-power operation. The presentation will conclude with practical design demonstrations illustrating these concepts in action.
