Rectifier Duty Transformers

Rectifier Duty Transformers are designed to handle non-linear, non-sinusoidal loads resulting from their use with a variety of power electronic applications such as diode, thyristor or motor drive configurations from 6,12,24,36,48, or 60 pulse configurations. Special design considerations should be used to account for the additional harmonic heating, more severe axial forces, severe overloads and short circuit forces that can be seen as compared with a standard power transformer. Niagara Transformer’s superior engineering expertise paired with its unmatched years of manufacturing experience and high-grade materials allow them to provide the best in-class Rectifier Duty Transformers.
