【Abstract】 Based on experimental model,a simulation model for inductively coupled power transfer(ICPT) system is constructed. Considering possibly non-ideal working condition of loosely coupled transformer,which may occur during actual application of IICPT system,the finite element simulation software ANSYS is used to analyze the variation tendency of inductance parameter of loosely coupled transformer under different air-gaps and different lateral displacements in transverse and longitudinal directions,and to validate the feasibility of above-mentioned simulation by experiment. To implement the decoupling between primary winding and secondary winding of loosely coupled transformer,the capacitance compensation for self-inductances of both windings under different frequencies is carried out and the impacting factors on system power and transferred efficiency under resonance respectively occurred in primary and secondary winding as well as the varying rules of system power and transferring efficiency with the variation of resistance,frequency and inductance parameter of the load are analyzed,to provide reference for optimization design of ICPT system.更多还原
