A steady-state analysis of high frequency-link resonant (HF-R) full-bridge dc-dc converters for inductive power transfer (IPT) systems for automotive and industrial battery charger applications are evaluated in this paper. For transferring power efficiently via the sending and receiving coils in the IPT systems, the inverter and rectifier operations together with output filter arrangement and the resonant tank should be taken into account in under the soft switching condition. The steady-state characteristics of series (S)-type, series / parallel (SP)-type, and series / series (SS)- type resonant full-bridge dc-dc converters are demonstrated and compared on the basis of theoretical and experimental analyses, after which the power converter architecture suitable for IPT systems is discussed from a practical point of view.
