This paper presents a methodology for multi-objective optimization of capacitive wireless power transfer (WPT) systems for electric vehicle charging that allows for a favorable tradeoff between power transfer density and efficiency. By quantifying the tradeoff between these two objectives, this multi-objective optimization approach can inform engineering decisions, given the requirements of a particular...
This paper investigates the tradeoffs involved in designing a single module in a multi-modular scalable capacitive wireless power transfer system suitable for stationary and inmotion electric vehicle charging. A matching network optimization is employed to design the module over a range of power levels, air-gap voltages, input and output voltages, and switching frequencies to evaluate impacts on its...
High-power large air-gap capacitive wireless power transfer (WPT) systems require matching networks that provide large voltage or current gain and reactive compensation. This paper introduces an analytical optimization approach for the design of L-section multistage matching networks for capacitive WPT systems. The proposed approach maximizes the matching network efficiency and identifies the optimal...
