Abstract :
Aluminum smelting is one of the most energy consuming industrial processes involving AC-DC conversion using highpower rectifiers. An overview is provided of the most effective power-system configurations employed in this industry. The most reliable and stable rectifier-transformer solutions and their impact on the AC side of the power network are described. Diode- and thyristor-based rectifiers, or AC-DC power converter systems, are compared. Models of the configurations of systems used in the Dubai Aluminium Company smelter power plant are simulated and measured.
