TLDR
In this paper, the area-product value of a resonant inductor is derived from the loaded-quality factor of a circuit, output power, and operating frequency assuming the window utilization factor and the maximum flax density.Abstract:
There are no well-established criteria for selecting the core for the design of resonant inductors. This paper presents new expressions of the area product for resonant inductors. By using proposed expressions, the area-product value can be calculated from loaded-quality factor of a resonant circuit, output power, and operating frequency assuming the window utilization factor and the maximum flax density. The area-product value expressed in terms of the loaded-quality factor is a good criterion for selecting the core. The design examples are given for single-wire winding and multiple-strand winding with a gapped core taking into account skin, proximity, and fringing effects.read more
