Abstract

Inductive power transfer (IPT) converters are resonant converters that optimize energy efficiencies at some loads. To achieve maximum efficiency, it is common to cascade the IPT converter with front-side and load-side dc-dc converters. The two dc-dc converters are normally controlled cooperatively in order to meet the requirements of output regulation and maximum efficiency tracking using a control technique based on perturbation and observation, which is inevitably slow in response. In this paper, a decoupled control technique is developed. The load-side dc-dc converter is solely responsible for output regulation while the front-side converter is responsible for impedance-matching of the IPT converter by controlling its input-to-output voltage ratio. The controls are linear and therefore fast. DC and small-signal transfer functions are derived for designing the control parameters. The performances of fast regulation and high efficiency of the IPT converter system are verified using a prototype system.
