Rectifier Transformers

Various rectifier and transformer connections are utilized for the various applications. For DC voltages in the lower range, the interphase connection is often preferred, while for the higher voltages and for the large processes, like aluminum, the bridge connection is more economical.

Rectifier transformers in electrolysis operation have normally a steady, but continuously high loading. The high secondary currents and LV bushing arrangements for large units, together with the secondary current harmonics in general, are essential design requirements to manage.
