AC/DC thyristor power converter – the Silcostat excitation system

Power Electronics


The Silcostat is an AC/DC thyristor power converter that supplies excitation current to the synchronous machine field. Our Static excitation system is the ideal solution for synchronous generators and motors.
The complete system includes the regulation control, power converter, field discharge (crow bar) and protection devices.

It is available with different cooling methods such as:

  •  natural air: up to 1850 A
  •  forced air: up to 3800 A
  •  forced water: up to 9000 A
