Abstract :
The paper describes an inductive power transfer system (IPT), by which electrical energy may be transmitted through a large air gap between coils without electrical connection. It presents theoretical and simulation analysis of IPT, which allows for supplying a receiver in the conditions of slow, in relation to the dynamics of power supply, changes in dimension of the air gap. The influence of frequency characteristics of the system on the possible selection of operation frequency range is discussed. Theoretical developments are compared with experimental results on the prototype IPT.
