Rectifier & Converter Transformers

Transformers for rectifier and converter applications have several purposes except transforming the voltage of feeding electrical network to the voltage level of the rectifier or frequency converter.

Converter and rectifier transformers are specially designed to withstand the current harmonics caused by the rectifier or frequency converter. These types of transformers are usually made with multiple secondary windings that are phase shifted (e.g. Dyn11d0) for achieving 12-, 18-, 24-pulse operation of the converter/rectifier. The higher pulse number the better harmonic reduction towards the supply network. The harmonic cancellation however means additional stress to the transformer active part because of additional energy losses. The balance of impedances between the multiple secondary windings is an important design parameter when making phase shifted transformers.

Converter and rectifier transformers are also equipped with an earthed screen between the primary and secondary windings to reduce the radio frequent disturbances, caused by the converter/rectifier, to towards the electrical supply network.

When special measures are made to the transformer design will it work without overheating even in heavy duty operation. This ensures overall good performance and a long lifetime of the transformer.
