Abstract

Inductive power transfer (IPT) technology has attracted more attention due to its convenience and safety. The mathematical model is an effective tool for analyzing and optimizing the performance of IPT systems. Many previous articles on modeling equate the load to a pure resistor, which can simplify the modeling process. However, this assumption is not reliable for the battery load. In this paper, the discrete-time model is derived for the IPT system with a constant voltage load. Four switching modes are defined in each cycle according to the switching states of the inverter and rectifier, the state equations are derived based on the equivalent circuit, and the discrete-time model is solved by iteration. Finally, simulations and experiments are both conducted to verify the accuracy of the established model.
