“…Furthermore, mirroring the classifications found within the DC-AC inverter topologies, the AC-DC rectifier circuits can be equally divided into two distinct clusters: a) Bidirectional Type, and b) Unidirectional Type, based on energy power flow direction. AC-DC rectifiers investigating bidirectional operation have been reported in [8], [88][89][90][91][92][93][94][95][96][97][98][99][100][101][102][103][104][105], [114][115][116][117][118][119], [121], [125][126][127] and unidirectional capacity documented in [3], [5], [9], [106][107][108][109][110][111][112][113], [120], [122][123][124] references. Within the realm of the single-stage topology, we can delve deeper and create further subcategories, primarily based on two essential aspects: a) Auxiliary Circuit Configuration, and b) DC-side Converter Drive.…”

“…The front-end AC-AC conversion step is typically executed via a 3x1 or 3x2 MC employing bidirectional switches ranging from 6 to 12. Some notable exceptions are reported in the literature, where different circuit structures are reported: a) an external clamp circuit for false current commutation of the MC in [97], b) LCL type input filter in [98], c) center-tapped HFT in [99], and d) MC with short-circuit leg in [100]. Additionally, several studies [101]- [105] have also investigated DAB-based converter derived from the rear-end FBC-based AC-DC rectifier topology.…”

The isolated AC-AC/DC-AC/AC-DC matrix converter (MC) is an innovative topology with several benefits including minimum current harmonics, nearly unity power factor, four quadrant (4Q) operation, and bidirectional power flow, making it an ideal choice for energy conversion techniques. Unlike any other AC-AC/DC-AC/AC-DC topologies, the MC topology necessitates electrical medium-frequency (MF)/high-frequency (HF) isolation in order to offer single-stage power conversion. MF/HF power conversion topology has numerous advantages such as high-power density, reduced weight, and low noise while preserving converter’s efficiency, cost, and reliability. This paper aims to report an extensive analysis and classification of different conventional isolated single-stage AC-AC converter, DC-AC inverter, and AC-DC rectifier topologies along with their modified system architecture. In this paper, the AC-AC/DC-AC/AC-DC topologies are classified based on their system architecture, AC-side or DC-side drive techniques, and other subvariants. Our primary objective of this study is to impart a clear understanding of the overarching framework and principles of the isolated AC-AC/DC-AC/AC-DC MC topologies and stimulate the creation of new topologies that cater to specific grid-interconnection requirement.
