Dynex Phase Control Thyristors
Dynex Semiconductor’s phase control thyristors can be used in any application requiring energy efficiency, switching at line frequencies and not requiring the switch to have turn-off capabilities.
Product Introduction
The Dynex Phase Control Thyristor is used in DC drives, Static Transfer Switches, Frequency Converters, Line Commutated HVDC Converters, Controlled Rectifiers, Static VAR compensators, in fact, any application requiring energy efficiency, switching at line frequencies and not requiring the switch to have turn-off capabilities.
Dynex Semiconductor’s phase control thyristors are produced in both Lincoln, England and Zhuzhou, China. Development continues to produce designs with lower losses, higher blocking voltages, higher current capability and devices tailored for particular applications.
Application
Thyristors are typically used in AC to DC converters (Rectifiers) which employ phase control to vary the average voltage on the output of the converter or switch the AC supply on and off. Operating at line frequencies where switching losses are small, the low conduction losses of phase control thyristors make for high system efficiency. Voltages range from 1200V used with domestic supplies to 8.5kV for medium voltage applications. Their high overload capability makes them ideally suitable for fuseless applications.
Product Features
• Current ratings from 370A average to 7610A average
• Voltage ratings from 1400V to 8500V
• Full blocking voltage capability at line frequencies from -40°C to + 125°C
• High surge current capability
• High di/dt turn-on capability
• High dv/dt capability
• High DC blocking stability
• Low conduction losses
