This paper presents a technique for extending the operating frequency of an inductive link used for wireless power transfer. The extension is achieved by segmenting the primary inductor. A circuit model is proposed for a single-coil squared inductor, which provides the basis for the model of the segmented inductor. These models help to understand the operation of the segmented inductor and serve as...
In design of a parallel resonant Induction heating system, choosing a proper capacitance for the resonant circuit is quite important. The capacitance affects the resonant frequency, output power, Q-factor, heating efficiency and power factor. In this paper, the role of equivalent series resistance (ESR) in the choice of capacitance is significantly recognized. Optimal value of the induction heating...
The need for a good capacitor model increases as the operating frequency approaches the Gigahertz range. A good capacitor model should fairly characterize the behavior of the capacitor to include other passive characteristics such as the resistance and inductance, not to forget the parasitic elements. Presented here is a method to extract lumped element models for metal finger capacitors. The model...
