“…Apart from these topologies, GTO or IGBT + diode based current source rectifier, other variants of thyristor rectifiers and modular topologies are also proposed for high-current applications; however, currently these topologies are not actively used in the industry [1][2][3][4][5][28][29][30][31][32][33][34].…”

“…Instead of thyristor rectifiers, a multi-pulse diode rectifier followed by a DC-DC chopper is proposed in the literature [1,2,4,5,[28][29][30][31][32][33][34]. Some companies are actively producing these units [1].…”

“…Diode‐ and thyristor‐based rectifiers are most commonly used for high‐power high‐current applications because of their proven reliability, availability of suitable ratings of semi‐conductor switches, robustness, long life and simplicity of the solutions [1–5]. Depending on the power levels and other application‐specific requirements, different types of configurations are used in the industry: Multi‐pulse diode rectifier with tap‐changing transformer and saturable reactor. Multi‐pulse thyristor rectifier with tap‐changing transformer. Multi‐pulse thyristor rectifier with passive filters. Chopper–rectifier (multi‐pulse diode rectifier followed by multi‐phase chopper). Apart from these topologies, GTO or IGBT + diode based current source rectifier, other variants of thyristor rectifiers and modular topologies are also proposed for high‐current applications; however, currently these topologies are not actively used in the industry [1–5, 28–34].…”

“…Segregation of the applications is carried out depending on the electrical characteristics of the load. Then, rectifier topologies used in industry are introduced and their applications, advantages/disadvantages and other salient features are described [21–34]. Power‐quality issues with thyristor rectifiers are highlighted and various compensation techniques proposed in the literature are discussed briefly [6, 35–61].…”

Applications such as electrolysis, electrowinning, DC arc furnaces and plasma torches require high-current (several kA) power supplies at low-voltage levels (few hundreds of volts). In this study, conventional rectifier topologies (diode-and thyristor-based multi-pulse rectifiers with on-load tap changing transformer and chopper-rectifier) used for high-current, variable-voltage applications are reviewed along with recent advancements in the field. The main applications themselves are also discussed. Issues with conventional topologies are highlighted. Power quality techniques like passive and active filters are discussed for power factor and current harmonics compensation. Advanced medium-to high-frequency transformer-based topologies (with current and voltage source rectifiers) are discussed along with simulation results.
