Double star and double bridge
Applications:
The rectifier transformers are mainly used in the electrolysis processes for production of different kind of metals, such as aluminum electrolyzing, magnesium electrolyzing, copper electrolyzing, zinc electrolyzing and other more applications. The largest installed rectifier transformers are always for aluminum electrolysis with some transformer/rectifier combined units in parallel operation to get the required DC current.
Design:
The rectification method is normally known as double star or double bridge. Double star systems use an interphase transformer (IPT) and are usually applied as 6 or 12pulse units where high currents are required with very low nominal voltages. Double bridge system is applied as 6, 12, 24, 48 or 60pulse systems, as required to suit the harmonic mitigation and process stability requirements.
Duty
Electrolysis is normally a continuous process, but with a constant high loading and current harmonics.
