Abstract

Due to the continuously increasing demand on switched-mode power converters (i.e., dc-dc, dc-ac, ac-dc, and ac-ac) that can achieve high efficiency at high switching frequency, soft-switching techniques have received much attention in the area of power converter applications over recent years. This article provides a comprehensive review of the state-of-the-art soft-switching techniques used to achieve the zero-voltage switching and zero-current switching supplied by power switching devices. First, the auxiliary-circuit-based and nonauxiliary-circuit-based techniques that perform soft switching are systematically classified according to power converter. Next, soft-switching techniques for each power converter are comprehensively classified and reviewed in detail. Unlike the existing review papers that only categorize the soft-switching techniques used in dc choppers and inverters, this article offers further helpful categorization for all types of power converters. Further, it provides the merits, demerits, and suitable applications for each soft-switching technique. Finally, it suggests future research issues for soft-switching techniques in power converters.
