摘要：

In this paper, a general analysis on wireless power domino-resonator systems with noncoaxial axes is presented. The mathematical formulation established can in principle be used to analyze wireless resonator systems with various domino forms. In this study, it is used to analyze and evaluate wireless domino-resonator systems with circular structures because such structures have more than one main power flow paths and have not been analyzed previously. Based on the superposition method, individual power flow paths are analyzed and then their interactions are emerged and explained with vector diagrams. Unlike the resonator pair used by Tesla, it is demonstrated that optimization of the domino systems can be achieved under "nonresonance frequency" operation and optimal load conditions. The shift of the optimal frequency from the resonance frequency is due to the multiple power flowpaths. The theoretical results have been favorably verified with practical measurements obtained from two circular systems.
