The shift rectifier transformer is a kind of transformer. It is a power transformer of rectifier equipment. The characteristic of rectifier equipment import current in original part and output direct current in another part. Change current is the generic terms of rectification, countercurrent and frequency conversion. The rectifier use widely among them. The transformer used as the power source of rectifying device is called rectifying transformer. Most industrial rectified DC power supply is obtained by ac power grid through rectifying transformer and rectifying equipment.

The transformer adopt multi-windings structure. The winding designs are the same. The phase position shift certain angle to achieve 6n pulse wave frequency conversion. In the theory, the harmonic wave below 6n could counteract. So this kind of transformer also called perfect wave transducer. The rectifier transformer is cake-type structure of windings. It has low voltage with layers. The turn insulation is NOMEX which has low partial discharge or no partial discharge.

The shift rectifier transformer is not affected by the structure of the conventional power transformer, and its structure and arrangement are various. According to the needs of the customers, the transformer winding can be made into two kinds of circular and rectangular. The circular winding transformer is suitable for the cabinet space and the volume of the whole transformer is large. The structure has good ventilation and heat dissipation. The rectangular winding transformer has compact structure and small size, but the ventilation and heat dissipation effect is not as good as the circular winding, so the rectangular winding transformer has higher requirements on the air duct design.
