Gate Turn Off Thyristors

Dynex Semiconductor is committed to the continued manufacture of GTOs to service the maintenance market that exists because of the long service life of traction equipment.

  • Gate Turn Off Thyristor

Dynex GTO Thyristor Range

The Gate Turn-off Thyristor has an inherent fast turn-on but is really designed to be turned off from a high current making it useful in PWM and chopper circuits. Dynex Semiconductor’s range of GTOs was primarily designed for use in railway traction and light rail propulsion drives and auxiliary converters although they have found use in other applications such as early STATCOMs.

Dynex GTO Thyristor Range

Applications

Applications for GTOs are those that require DC to be turned on and off in a controlled manner. Such applications include AC motor inverters, choppers and DC-DC converters.
