This paper proposes a three-phase interleaved highfrequency transformer isolated ac-dc converter that is suitable for small scale wind energy conversion systems employing permanent magnet synchronous generators. This configuration is realized by interleaving three identical single-phase singlestage ac-dc converters obtained by integrating a rectifier, boost converter and fixed-frequency dual-tank LCL resonant converters. Based on a design example used for illustration purpose, a converter is
