PROJECT TITLE :
Analysis and Design of Loosely Inductive Coupled Wireless Power Transfer System Based on Class-$^$ DC-DC Converter for Efficiency Enhancement
This paper presents a design procedure of high-frequency loosely inductive coupled wireless power transfer (LIC-WPT) system based mostly on class- dc-dc converter, taking into account the power loss reduction of inverter, coupling part, and rectifier simultaneously. Analytical expressions including the dc-to-dc potency of the WPT system are derived and also the efficiency deterioration mechanism is explained by the circuit model. Through the analytical expressions, the look procedure for satisfying each the class-E switching conditions and power loss reductions at the coupling part is proposed from the circuit-theory viewpoint. The class- WPT system designed by the proposed design procedure achieves high dc-to-dc potency at low coupling coefficient, in explicit, compared with those designed by the previous style strategies. The validity and effectiveness of the proposed style procedure were confirmed by PSpice simulations and circuit experiments.
