Control subsystem design for wireless power transfer

Abstract

Recently, the wireless power transfer has been increasingly employed. Particularly for the electric vehicles, the wireless solution is attractive for contactless battery charging, based on the Inductive Power Transfer (IPT). In this paper, a 150W prototype for IPT-based battery charging is presented and design criteria are reported. In addition to the power stage analysis, a proper control strategy is proposed. Simulation and experimental results are shown. The proposed control method aims at regulating the load current against variations in the magnetic coupling, so that the required amount of power can be supplied despite of unexpected decreases in the coupling efficiency

Design and Realization of a Bidirectional Full Bridge Converter with Improved Modulation Strategies

“…Due to the potentially high voltage range of a stack of supercapacitors, proper DC-DC converter architectures could be used-in References [18][19][20][21] high-voltage-ratio topologies are described, feasible for several applications such as automotive, DC microgrids and renewable energy sources. At the same time, such high voltage levels could suggest the use of galvanic isolation in order to guarantee safety-in References [22][23][24][25][26][27] different applications of isolated DC-DC converters for energy storage management are reported.…”
