Abstract

High temperature superconducting (HTS) technology is a good choice for developing high-power high-efficiency wireless power transfer (WPT) device because the HTS coils have very high critical current and nearly zero resistive loss. This paper investigates the modeling of self-inductance and mutual inductance between the primary and secondary ReCBO pancake coils used in HTS WPT systems. Half-analytical and half-numerical methods are adopted and verified by both the FEM simulations and practical experiments. The developed models and calculating method of mutual inductance lay some technical bases for forming a feasible designing scheme in practical HTS WPT systems.
