A High Frequency (HF) inductive power transfer circuit for high temperature applications using SiC Schottky diodes

Abstract

Wireless sensors placed in high temperature environments, such as aircraft engines, are desirable to reduce the mass and complexity of routing wires. While communication with the sensors is straight forward, providing power wirelessly is still a challenge. This paper introduces an inductive wireless power transfer circuit incorporating SiC Schottky diodes and its operation from room temperature (25 °C) to 500 °C.
