Abstract
This paper presents a version for three-phase three-level unidirectional rectifier employing a passive lossless snubber. The proposed rectifier operates with soft commutation without the employment of auxiliaries switches. As a consequence, its efficiency is high and its cost is low. Circuit operation, theoretical analysis, design procedure and experimental results are presented
