Summary: This letter presents an enhanced-fundamental-harmonic-analysis (EFHA) method to accurately derive the output current model of LCC-P compensated IPT system based on the steady-state operating waveforms in a time domain. The results show that the output current of LCC-P compensated IPT converters would degrade with the load resistance and only quasi-CC output can be achieved within a certain load range.

Summary: This article proposes a hybrid IPT system for EVs charging applications, which has high misalignment tolerance and inherent CC-CV output. By applying two coils connected reversely in series on the transmitter side and two coils compensated by a capacitor and an inductor-capacitor-capacitor on the receiver side, natural CC-CV output is achieved without the need for an extra dc-dc converter or complicated control strategy. The experimental results demonstrate the stability of constant charging current and constant charging voltage within the predetermined misalignment range.

Summary: This letter proposes an inductive power transfer system that can maintain stable output power in an ultrawide coupling variation range. Taking series-series compensation as an example, the study defines two general impedance factors to investigate the theoretical limit of detuned compensation. By using circuit transformation, various detuned compensations can be studied in a unified manner and used to explain the mechanism of the proposed LCC/S-S system. The consideration of soft-switching is incorporated in the design of proper factors. When the proposed compensation is implemented in a real system, it naturally ensures a 20% power fluctuation within an ultrawide coupling coefficient range (from 0.07 to 0.33) and maintains an efficiency above 80%.
