Abstract：An inductive power transfer (IPT) system requires a feedback controller to stabilize the output, which highly depends on an accurate small-signal model. In the past years, the extended describing function (EDF) is widely used to address the modeling issue for resonant converters. However, the high-order resonant tank of IPT would lead to a complicated model if EDF is directly applied. In order to simplify the model, this paper explored a circuit-based method to reduce the order for both series and parallel resonant circuits. An example LCC-C compensated system was used to explain the concept. This general simplification can be extended to any other high-order IPT systems.
