How does a rectifier work?

Rectifiers convert the 3-phase supply voltage to DC voltage. More sophisticated systems allow feeding back surplus energy into the MV grid. DC switchgear and voltage limiting devices serve as control and protection equipment. Energy storage systems are used for peak shaving and voltage stabilization in traction systems.

What is a high-current rectifier system?

Power Conversion's high-current rectifier systems are an optimized and flexible solution to meet large scale solutions for many heavy industrial processes such as electrochemical, hydrogen production and other specialized applications. Our offering will support configurations from 0 kA to 45 kA of DC output current.

Which rectifier technology is used in industrial applications?

The rectifier technologies employed in industrial applications are commonly known as double star (DSS) or double bridge (DB). DSS systems use an interphase transformer and are predominately applied as 6- or 12-pulse units where high currents are required with very low nominal voltages.

What are Hitachi energy rectifiers used for?

Hitachi Energy's rectifiers are combined with a diode or thyristor rectifier. Applications range from large aluminum electrolysis to medium size operations. The transformers can be equipped with a built-in or separate voltage regulation unit.

What are energy storage systems used for?

Energy storage systems are used for peak shaving and voltage stabilization in traction systems. ABB offers a full range of rectifiers in line with EN 50328 and IEC 62590 connection schemes. ABB provides a comprehensive range of rectifier transformers and diode rectifiers in different technologies, configurations and ratings.

Can A Rectiformer be supplied as a single tank?

Rectiformers can be supplied as a single tank solution for applications up to a rating of approximately 160 MVA, but for larger ratings, transport limitations normally require that two transformers be supplied as separate units. Quality is a priority for Hitachi Energy.
