Abstract

See full text

An inductively coupled power transfer (ICPT) system includes a primary winding for generating an electromagnetic field (EMF), and an ICPT device. The ICPT device includes a phase detecting winding which generates a detecting voltage according to the EMF, a resonant circuit which has an adjustable reactance and which generates an AC voltage according to the EMF and the adjustable reactance, and a control circuit which compares a phase of the AC voltage with a phase of the detecting voltage so as to determine whether said resonant circuit operates in an under-tuned or an over-tuned interval, and which varies the adjustable reactance according to the output voltage and one of the under-tuned and over-tuned intervals.
