The fundamental principle of a novel wireless power transfer(WPT) technology is investigated in this paper through coupled mode theory. The concept of strong coupling is proposed considering coupling effect between eletromagnetic(EM) waves. It is simulated by equivalent circuit method and validated by experiment.
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...
Contactless electrical energy transmission system (CEET) which can work under atrocious conditions realizes contactless transmission between power and loads. It is necessary to improve the efficiency of the detachable transformer, as it plays an important role in the system. Based on the structure and work principle of the system, related parameters are analyzed in this paper. Detachable transformer...
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...
