Design considerations for a contactless electric vehicle battery charger
TLDR
This paper overviews theoretical and practical design issues related to inductive power transfer systems and verifies the developed theory using a practical electric vehicle battery charger.Abstract:
This paper overviews theoretical and practical design issues related to inductive power transfer systems and verifies the developed theory using a practical electric vehicle battery charger. The design focuses on the necessary approaches to ensure power transfer over the complete operating range of the system. As such, a new approach to the design of the primary resonant circuit is proposed, whereby deviations from design expectations due to phase or frequency shift are minimized. Of particular interest are systems that are neither loosely nor tightly coupled. The developed solution depends on the selected primary and secondary resonant topologies, the magnetic coupling coefficient, and the secondary quality factor.read more

Comparative Analysis of AC - AC Power Converters for Primary Side Wireless Power Transfer System
TL;DR: Two versions of converters are reviewed: first version rectifies the grid supply through Power Factor Correction circuit and improves the quality of the input current and then using High Frequency Inverter, it is converted to high frequency AC supply that is fed to the transmitting coil, while the second version receives thegrid supply at fundamental frequency and directly converts in to the high frequency to supply the transmitting Coil.
