Contactless power delivery system for mining applications

Abstract

The authors present the application of a power delivery system design unifying power electronics and a coaxial-winding transformer for devices that require contactless connection and/or relative motion while delivering large amounts of power. The transformer's unique characteristics and how they might be used to advantage in combination with power electronics are emphasized. Applications which have near-term realizability are flexible power distribution, material handling, autonomous electric vehicles, and battery opportunity recharge. Test results on a scale prototype are presented to verify the concepts.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
