The Vienna rectifier can produce three voltage levels, however only the connection to the
neutral-point is fully controllable using the bidirectional switches. When the neutral-point …

Three-phase three-level unidirectional rectifiers are among the most adopted topologies for
general active rectification, achieving an excellent compromise between cost, complexity …

Vienna rectifier is a unidirectional three-level ac–dc converter, which is widely used in many
applications. For Vienna rectifier, the current zero crossing distortion (CZCD) is usually …

In parallel T-type three-level rectifiers system (PT 2 3LRs), when the open-circuit fault (OCF)
of neutral-point (NP) switches occurs, the existing zero-sequence circulating current (ZSCC) …

This paper proposes an improved zero-current distortion compensation (IZCDC) method for
the Vienna rectifier. The conventional zero-current distortion compensation (ZCDC) method …

The transportation sector is one of the major contributors to the global greenhouse gas
generation and is thus subject to considerable political attention. In view of the increasing …

The production of green hydrogen, reliant on renewable energy sources, stands as a
sustainable and carbon-neutral alternative in the fuel landscape. A pivotal aspect of this …

The three level Vienna rectifier has an inherent problem of current distortion at zero
crossings. This can be mitigated by injecting a particular zero sequence so that the …
