Thyristorised Converter

The thyristor rectifier is an established and reliable technology that has been used for decades with great success. Thyristor rectifiers have a high efficiency, good load current regulation, and the ability to scale to very high power levels. Thyristor rectifiers are suitable for rugged topologies.

Ador Powetron provides 6 pulse, 12 pulse, 24 pulse and 48 pulse thyristorised converters across the world for various application and of various ratings.
