Study and design considerations of three-phase bi-directional AC/DC converter

By now, three-phase bi-directional AC/DC converter has been developed to an advanced level with the property of high efficiency, high power quality, low cost, enhanced reliability. This paper makes a detailed review of three-phase bi-directional AC/DC converters, and explores a broad perspective on different topologies and control schemes to designers, application engineers and end users. At last, this paper presents some design considerations, which saves time and cost of development for designers and bring about great convenience for end users and engineers.
