In this paper, the principle of wireless power transmission technology based on resonant coupling is discussed. A simplified equivalent circuit modeling for wireless power transmission system is established. A resonator constituted by single-layer helical coils is designed and investigated. Based on experiments, the output load voltage correlated with different distance, driving frequency and disalignment...
In this paper, a resonant coupling wireless power transmission system whose resonator using single-layer helical coils is designed. Based on analysis of equivalent circuit, the efficiency and optimal transmission distance are obtained, and its correctness is verified by experiment. The resonant frequency and electromagnetic field distribution of system are obtained through high frequency finite element...
Contact-less electrical energy transmission system has become more and more attractive in power transmission area these years because there is no direct electrical connection or physical contact between the energy transmission system and the power receiver. This paper presents the function principle of contact-less electrical energy transmission systems and new developments. Equivalent circuit model...
This paper presents a magneto mechanical coupling hysteresis model for a magnetic force control device based on the Jiles-Atherton equation, the law of approach equation and the equivalent magnetic circuit of the device, and determines the parameters of the model by the genetic algorithm. Comparisons between the calculated and measured results show the validity of the model
