Abstract

Abstract: In the traditional inductive coupled power transfer(ICPT) system which is compensated with fixed compensation capacity,its output voltage fluctuates with the change of load.Aiming at this shortcoming,a new ICPT topology based on bilateral dynamic capacitance compensation with magnetic energy recovery switch(MERS) was proposed,which makes the compensation link of the ICPT system controllable.The topological analysis and modeling were conducted by mutual inductance theory and loosely coupled transformer leakage inductance model,and the mathematical relationship between MERS,output voltage and power factor of inverter was established.By using the dynamic compensation of transmitter,the reactance component of the system input impedance can be offset,and the power factor was increased.Through the dynamic compensation of receiving terminal,the influence of load variation on output voltage can be weakened,so that the output voltage remained stable.At last,an experimental device for 5 V voltage output was set up,the power factor of the inverter was stable around 0.9 in the range of load change,which proves the voltage regulation and power factor adjustment function of this topology when the load was changeable.

Key words: inductive coupled power transfer(ICPT), magnetic energy recovery switch(MERS), compensation with dynamic capacitance, power factor
