CONTACTLESS POWER TRANSFER FOR ROTATING APPLICATIONS USING MAGNETIC COUPLE

Abstract: Contactless power transfer systems are increasingly used in rotating and sealed applications where traditional wired connections and slip rings suffer from wear, sparking, and maintenance issues. This project presents a Contactless Power Transfer System for Rotating Applications using Magnetic Coupling, designed using an Arduino-based control unit. The system employs inductive magnetic coupling between a stationary transmitter coil and a rotating receiver coil separated by a small air gap. The Arduino generates a high-frequency switching signal that drives a power electronic circuit connected to the transmitter coil, producing an alternating magnetic field that enables wireless power transfer.
