“…Moreover, considering the power flow direction, the classification of DC-AC inverter topologies can be further refined into two distinct groups: a) Bidirectional Type, and b) Unidirectional Type. Notably, existing literatures revolving around DC-AC inverter investigate bidirectional capability within [4], [6][7], [10][11], [41][42][43][44][45][46][47][48][49][50][51], , [78][79][80][81][82][83][84][85][86] and unidirectional functionality as reported in [52][53]. • MC HFL Type: In our study, the focus is on the single-stage MC HFL type DC-AC network, which basically encompasses a MC within the network.…”

“…One key challenge to employ this topology with non-isolated DC-DC converters is that it leads to design complexity. l) 2SL Inverter: Reference [78], has introduced a bidirectional DC-AC inverter employing 2SL inverters for EV charging or 3P AC grid integration. Adaptation of decoupled HFT has led to zero LF pulsations in the instantaneous power across the transformer which further reduce DC-link capacitor requirements as opposed to DAB-based configuration.…”

“…Likewise, reference [13] diligently undertook a comprehensive classification of isolated MCs based on AC-side drive techniques. However, this review [46] [47] [48] [ [49][50][51] [ [52][53][54][55] [56] [4,6,42,[67][68][69][70][71] [7, [57][58][59][60][61][62][63][64][65][66] [72] [73][74][75][76] [77] [78] [79] [57,[80][81] [89]…”

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.
