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