Self and Mutual Inductance Behavioral Modeling of Square-Shaped IPT Coils With Air Gap and Ferrite Core Plates

“…We have further validated the discovered self-inductance model ( 6) by proving the generalization capability of the model coefficient laws given in ( 7) and ( 8). I and satisfying the feasibility constraints (2). For all the considered validation test conditions, the percent errors of the model ( 6)-( 8) are very low, with the maximum percent error of 12.2%, as depicted in Fig.…”

“…The design of an Inductive Power Transfer (IPT) link involves system-level specifications that must be matched with a proper choice of architectures and components [1]. System-level requirements usually involve power, voltage and current ratings, switching frequency and source type [2]. In addition, the chosen architecture has an impact in the resonance method [3] [4].…”

Advanced Wireless Power Transfer Technologies : Reactance Cancelling and Inverse Coupled Current Doubler Rectifier

“…In [51], a current-fed parallel resonant push-pull inverter is proposed for WPT to reduce the conduction losses on the switches. Various combinations of compensation topologies (series or parallel) have been investigated in [54], [55], [56], [57] to improve coil link efficiency. High-order resonant circuits such as LCC are also investigated particularly for dynamic charging of electric vehicles [58].…”

“…The main reasons for this decision are: zero voltage switching (ZVS) behavior in the inverter stage along the whole operating frequency range and the requirement of regulating under a wide power range. In [54], different compensation approaches are analyzed, identifying these advantages in the series-series resonant network behaving as a voltage source. The compensation capacitors placed in series with the coils are tuned with the leakage inductance as in [54], by doing so, it is possible to achieve a constant voltage source.It is worth noting that the ICCDR can be used in different compensation approaches of a S-S WPT system (current source or voltage source).…”
