摘要: 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- thyristor-based multi-pulse rectifiers with on-load tap changing transformer chopper-rectifier) used for high-current, variable-voltage applications are reviewed along recent advancements in the field. The main themselves also discussed. Issues highlighted. Power quality techniques like passive active filters discussed factor current harmonics compensation. Advanced medium- to high-frequency transformer-based (with voltage source rectifiers) simulation results.
