TL;DR: In this article, the relationship among compensation parameters, circuit efficiency, voltage transfer function, and conduction angle of the input current relative to the input voltage are studied, and a design and optimization method is proposed to achieve a better overall efficiency as well as good output voltage controllability.

TL;DR: In this article, the authors studied the characteristics of the IPT system at various frequencies of operation utilizing the two compensation techniques to work as a voltage converter and compared the optimal frequencies corresponding to the two compensations to facilitate the design of voltage converters with efficient power conversion and load independent frequency of operation.

TL;DR: It is shown that TL converters are highly suitable for high input/output voltage and medium-to-high-power dc-dc power conversions and the virtues and drawbacks of these converters as compared to conventional converters.

TL;DR: A control method is proposed to lock the switching frequency at just above the load insensitive frequency for optimized efficiency at heavy loads and a prototype transcutaneous power regulator is built and found to to perform excellently with high efficiency and tight regulation under variations of the alignment or gap of the trans cutaneous transformer, load and input voltage.

TL;DR: In this article, a series/series-parallel (S/SP) compensation topology was proposed to achieve both high efficiency and good output controllability in contactless power transfer systems.
