The rectifier transformer is acting as link between the grid and the AC to DC converters. Application of rectifier transformer is to provide required number of phases, voltage shifts needed to realize the conversion and to adjust the rectifier input to vary the DC output voltage. Rectifier transformer is generally used in various applications such as electrolysis process, aluminium smelting, graphitizing etc.

Rectifier transformers are associated with very high secondary currents encompassed with huge harmonic content caused by semiconductors devices connected to transformer.
