The majority of wireless power transfer (WPT) systems transfer power in a directional manner. Recently, omni-directional WPT systems have been addressed by several research groups. This paper describes a discrete exciting voltage control technique for wireless power transfer via magnetic resonant coupling with multiple orthogonal transmitter coils which can maximize the power transfer efficiency in...
Recent years have witnessed the booming development of resonant wireless power transfer (RWPT). Compared with conventional inductive power transfer, the frequency of RWPT is usually much higher. To reduce the resonant frequency while maintaining the transfer efficiency constant at the same transfer distances, two solutions are proposed and realized in this letter. Two fundamental structures for RWPT...
Although 60 W wireless power transfer was demonstrated in 2007, still there is no equivalent circuit model for a sub-meter air-gap, hundreds of Watts, high efficiency wireless system. A design-oriented circuit model is needed for this technology to evolve. This paper proposes an equivalent circuit model for the wireless system and analyzes the system based on the proposed model. The proposed model...
