Abstract
Power electronic resonant converters designed for inductively coupled power transfer (ICPT) applications are normally controlled to switch at zero vol tage switching (ZVS) frequencies and operate with minimal quality factor Q for economic and practical reasons. This Letter analyses various resonant f requencies and defines a new minimum bound on Q that ensures ZVS operation.
