[Abstract]:Wireless Power transfer (WPT) technology has made a series of achievements in theoretical research and engineering technology, and has been applied in many fields such as electric vehicles, mobile robots, intelligent manufacturing and so on. Among them, electric field coupled power transfer (ECPT) system adopts electric field as power transmission medium, which is highly concerned by experts and scholars at home and abroad because of its unique advantages, and the coupling mechanism is designed around the electric power transformation topology of ECPT system. A large number of researches have been carried out on the original edge constant current control, and some theoretical results have been obtained, and they have been applied in the fields of aerospace motor, electric vehicle, biomedicine, lighting appliance, tablet computer charging and so on. In this paper, the research status of ECPT system at home and abroad is described, and the working principle and advantages of ECPT system are briefly introduced. Then, the current power conversion topology of ECPT system is analyzed in detail. On this basis, in order to solve the contradiction between the high voltage excitation demand of coupling mechanism and the low voltage demand of switching tube MOSFET in the link of high frequency power conversion. In this paper, a new type of circuit topology is presented, which adopts the resonant circuit of Con CLC at the transmitter and the circuit with the series compensation of the S type at the pickup end, based on the analysis of the frequency characteristics, the power transmission characteristics and the voltage transmission characteristics of the ECPT system model. The parameter configuration method of resonant circuit with the effect of voltage pump between plates is presented, and the sensitivity of the system is analyzed. In this paper, a stepless tuning method based on phase-controlled inductors is proposed to reduce the transmission performance of the new ECPT system caused by the change of transmission distance. It is realized that the system always works in the resonant state when the transmission distance varies in the range of 1-5mm. The transmission power and working stability of the system are improved, and the tuning control circuit and its related software are designed for the new ECPT system. Finally, the simulation model is constructed based on Matlab / Simulink platform, and the corresponding ECPT experimental device is built. The simulation and experimental results verify the validity and correctness of the proposed circuit topology and tuning method.
