Energy Model and Characteristic Analysis for Inductively Coupled Power Transfer System
摘要
Abstract
Inductively coupled power transfer (ICPT) is based on the principle of electromagnetic induction and is currently adopted using the theory of the circuit model.Because of the defect that this method is unable to help understand the energy transfer process of ICPT system,an energy modeling method of ICPT system is proposed.The energy models of four kinds of ICPT systems are created, including series-series, series-parallel, parallel-series and parallel-parallel topologies. The relationship between energy model and coupling mode is discussed,their equivalence and equivalent conditions of mathematical meaning are studied,and simulation results by MATLAB have verified the theoretical implications.Furthermore,in view of the phenomenon,the principle of ICPT and that of magnetic coupling resonant wireless power transfer (MCRWPT) are confusing,the difference in the principle of ICPT and MCRWPT are enunciated,which is based on the energy mode.It is concluded that ICPT system is equivalent to MCRWPT system of SS topology only when it meets the resonant condition,weak coupling and the coils with high quality factor,thus clarifying the differences in the principle of ICPT system and MCRWPT system,which can provide references for further design and optimization of ICPT system and MCRWPT system.关键词
