Generalized Hamiltonian Energy Modeling Method for Wireless Power Transfer System

Wireless power transfer (WPT) system is a typical multi-mode, nonlinear, uncertain, high-dimensional system, and system modeling is relatively difficult. This paper proposed an energy modeling method based on Hamilton realization to overcome the limitations of traditional modeling and analysis methods due to system complexity. In this paper, a generalized Hamilton energy realization model of a capacitive power transfer (CPT) system based on double-sided LC-compensated network is established to study the property of the model specification characteristics. From the energy analysis of CPT systems, explaining the dynamic energy changing principle of the electromagnetic conversion process and revealing the principle of wireless power transmission. The simulation results show relations between the energy invariance of the stored energy, and verifies the accuracy of the Hamilton energy model.
