General Method

<pre>This paper proposes a new and general method to optimize a working <br />frequency and a load resistance in order to realize highly efficient wireless <br />power transfer. It should be noticed that neither resonant frequency nor <br />matched impedance maximizes efficiency of wireless power transfer circuit, <br />in general. This paper establishes a mathematical model of a commonly <br />used wireless power transfer circuit, and derives a mathematical expression <br />of circuit efficiency which involves a working frequency, a load resistance and <br />the other parameters as symbols. This enables us to find the optimal working<br />frequency and load resistance. The result of this paper is compared with <br />results by a method based on resonance and impedance matching, and then <br />clarified by a numerical example.</pre>
