A study on performances of different compensation topologies for loosely coupled inductive power transfer system

This paper investigates the performance of different compensation topologies of loosely coupled inductive power transfer system at 1MHz using Class E Amplifier. The capacitor compensation technique is regularly used in inductive power transfer to solve the problem of large leakage inductance and get the maximum power transfer when reach the resonant inductive coupling. In this paper, the analysis of efficiency of power transfer for four compensation topologies will be considered, which are primary series-secondary series (SS), primary series-secondary parallel (SP), primary parallel-secondary series (PS) and primary parallel-secondary parallel (PP). The performance of such topologies is evaluated through the simulation results.
