Applying LCC Compensated Primary Topology Utilizing Switches for Transmitters With Inter-Coupling in a Wireless Power Transmission System

LCC compensation network is a commonly used primary compensated topology for wireless power transmission. In this paper, we investigate the utilizing switches two transmitters with strong inter-coupling. First, drawbacks of current are analyzed in aspects over-voltage, loss, and reactive power. Then, an modified switch location proposed to provide no extra loss additional idle coil. After that, connection modes investigated reduce over-voltage on switches. Finally, two-coil charging system built up confirm feasibility under inter-coupling, theoretical analysis performance verified.
