Abstract

In high power applications of wireless power transfer systems as Maglev, both a high transferred power and a high efficiency are essential. However, these two requirements usually show dissimilar profiles over a range of operating conditions. Magnetic and electric models for a capacitor compensated system are used to analyze the problem. Using the analysis outcome, a compromise is made to come to an acceptable design, achieving both requirements. In particular, appropriate design parameters and resonance frequency are obtained. The analytical results are confirmed by 3D FEM analysis.
