Abstract

In a wireless charging system, a back-end DC/DC converter can be used after the coil rectification stage to match the battery charging requirements and to optimize the resonant converter operation. In this paper, a synchronous boost converter is selected according to suggested coil parameters from SAE J2954 standards on a WPT1 3.7 kW power class. This converter is analysed while cascaded to a resonant converter with series-series (S-S) compensation. The semiconductor and inductor losses under hard-switched continuous conduction mode (CCM) and triangular current mode (TCM) are calculated and compared. A benchmark study shows that both the TCM and CCM operations have similar performance of efficiency in constant current (CC) charging profile while TCM has a higher efficiency in the constant voltage (CV) charging profile of a Nissan Leaf EV battery.
