AC-DC controlled rectifier

25,000 Vac > 1,500 Vdc or 750 Vdc

Our power electronics skills for SNCF maintenance centres

The controlled rectifier allows to generate different continuous current voltage levels from the catenary alternative current.

Doing so, it enables maintenance centres to simulate different continuous current phases and then test trains and trams in all the possible voltage configurations.

The AC / DC controlled rectifier can transform a 25,000 V single phase alternating current into a 1,500 V or 750 V regulated DC voltage. It can be integrated into a shelter or an existing building.
