Simulation and Test of a Single-Pancake Coil Wound by ReBCO Tapes

In the context of wireless power transfer (WPT) technology, low allowable current density and large resistivity of conventional copper conductors limit the increments of primary current and transfer efficiency. A new WPT scheme using high temperature superconducting (HTS) primary can be well expected to develop various high-power and high-efficiency WPT devices. This paper investigates the critical current and temperature field features of a single-pancake coil wound by ReBCO tapes. The experimental and calculated results lay some technical bases for developing practical HTS WPT devices.
