Overview of Single Conductor Power Transfer With Open-Ended Helical Resonators

摘要

This paper explores the operation of a single conductor power transfer (SCPT) system, utilizing two open-ended helical resonators. Contactless power transfer is established over a metallic structure by means of coils to couple energy to the resonators and to the load. The operation of the SCPT system is analyzed based on an analogy with conventional resonant inductive power transfer with two pairs of coils-resonators. Finally, two other methods for SCPT with helical resonators are outlined for comparison purposes.
