High power rectifier
ABB high power rectifier (HPR) systems are employed in electro-chemical electrolysis processes, graphite electrolysis plants, and DC-arc furnaces. Typically, such plants consist of at least a rectifier-transformer, rectifier power part, rectifier cooling unit and control system. We distinguish diode and thyristor rectifier.
Control systems
Large-scale power converters and drives must be reliable, fast and precise. That calls for a control system with outstanding performance. The AC800PEC is a high-end process control systems for high-speed control requirements as well as low-speed process control tasks.
