Abstract
A key requirement in inductive power transfer (IPT) systems is primary high-frequency voltage generation. Until recently, two power conversion stages (AC-DC-AC) were required to generate high-frequency voltage in the IPT systems. These systems are usually costly and cumbersome. Matrix AC- AC converters, highlighted by the absence of bulky DC link storage elements, are considered as a potential alternative. The removal of one power conversion stage enhances the system performance in term of efficiency, reliability, size, weight, and cost. Now, AC-AC buck, half-bridge, and full-bridge converters are gaining popularity in IPT applications. However, highly accurate analysis of their performance in the IPT systems is a challenge. In this paper, a simple and accurate mathematical analysis for the AC-AC buck converter supplying a series-series compensated IPT system is given. Performance indicators used for analysis are input power factor and power transfer capability. The accuracy of the analysis is validated through simulation. The analytical results presented in this paper can also be employed to analyze the series-series IPT system fed from other AC-AC matrix converters.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
