一类高可靠且高效的单级高频交流环节变换器

This paper proposes a new class of topologies of single-stage high-frequency ac-link power converters, which is capable of providing both voltage step up/down within a wide frequency and voltage ranges. The proposed family, which supports bidirectional power flow, can interface various single/multi-port dc and/or single/multi-phase ac systems to provide dc-dc, dc-ac, ac-dc, or ac-ac power conversi...
