Abstract


A contactless power transfer system at high frequency incorporating strong coupling between primary and secondary coils is very widely in mobile phones to replace the plug and socket charging. The primary and secondary coils coupled using resonant inductive coupling is modelled using compensation capacitors in the primary and secondary coupled circuits. Theoretical analysis of the system is presented and operating power transfer efficiency under varying conditions of source and load is derived. The model presents the variations in the contactless system for all possible variations in the parameters. Simulated results performed using Matlab at 600 kHz are presented.
