Summary
In this paper, analysis and design of a current controlled active rectifier on the secondary side of an inductive power transfer (IPT) system is presented. The secondary side controlled rectifier is designed to adjust the battery dc charge current by varying the effective load resistance seen at the secondary coil terminals. Steady-state performance of the IPT system is evaluated based on fundamental harmonic analysis. The current control and gate signal generation schemes of the whole system are built in a simulation model. Theoretical and simulation results of investigated control scheme are shown. Finally, the theoretical results are validated by experimental results obtained from the implemented laboratory prototype.
