Design of Misalignment Tolerant Control for an Inductive Charger with V2G Possibilities

Since the power transfer efficiency in inductive power transfer (IPT) systems is directly related to the coupling of the transformer, coil misalignment can drastically decrease the efficiency. In this paper a misalignment tolerant control scheme is proposed which tracks the maximum power transfer efficiency point under misalignment. It does this...

Comparative Study of Foreign Object and Misalignment in Inductive Power Transfer Systems

This paper aims to identify the difference between foreign object (FO) and misalignment in terms of their influence on inductive power transfer (IPT) systems. This is performed through magnetic and equivalent circuit analysis of the mutual inductance, primary input impedance, charging pad terminal impedance and current harmonics. Experiment...
