Application of current limiting inductance effect on class - E driver circuit for inductive wireless power transfer

This paper presents application of class - E driver circuit for inductive wireless power transfer. In this respect, an objective circuit is considered for a non-conductive housing telemetry unit consuming a minimum of 5 mA from a 5.5 V-regulated supply having maximum target distance is 70 mm. For this purpose, link optimization theory is used for designing exact link to select parameters of the objective circuit. In this prospect, a single 12V (drain to source) capacity MOSFET is used in the proposed driver circuit design. Results obtained from simulation shows that the proposed driver circuit provides a 5.5 V DC regulated supply to a distant load. In addition to that, acceptability of wireless power transfer is analysed from the view of performance parametric analysis.
