Abstract

This paper presents an analysis of series-series compensated unloaded inductive wireless power transfer system, without neglecting equivalent primary and secondary resistances. It is shown that equivalent first-harmonic-approximation based phasor-domain equivalent circuit underestimates the output DC voltage under these conditions, hence solution based on time-domain analysis is utilized to accurately predict the output DC voltage for a wide range of operation frequencies at resonance and inductive regions. The presented analysis is well-verified by simulation results of a 400V, 3.3kW inductive wireless power transfer link.
