We provide one of the most comprehensive ranges of standard phase control thyristors in the industry. Devices with voltage ranges from 600V to 4500V are available, making them suitable for applications with line voltages from 230V to over 1000V (higher voltage applications are now served by our range of Medium Voltage Thyristors). IXYS UK Westcode Ltd. is a leading supplier of phase control products into demanding markets such as industrial DC drives, induction melting, marine/rail propulsion systems, wind power converters, electrochemical power supplies and soft starters. These devices are optimised to give low conduction losses and are primarily intended for applications with line frequencies up to 400Hz.
The Wespack outline is a new concept in phase control thyristors for applications requiring devices rated to 2200V. It gives the maximum power rating for weight and volume without compromising on quality and reliability. It also gives the maximum current rating and lowest thermal resistance for the package size.
Phase Control Thyristors
The "P" series of fast switching thyristors have regenerative gate structure to ensure low switching losses and high di/dt performance. "P" Series devices are particularly attractive to; Inverter, DC chopper drives, UPS and Pulse Power applications. In additional to pressure contact technology these devices offer lower reverse recovery charge values, low forward switching losses and high reliability.
IXYS UK Westcode Ltd is recognised as the Worldwide leader in distributed gate technology. These devices are available with blocking voltages to 4.5kV and currents to 4kA, with tq from 10 to 300 micro seconds. The unique distributed gate design and lifetime control features give these devices both high di/dt capability and fast, low recovery turn-
Distributed Gate Thyristors
Medium voltage applications place additional demands on phase controlled thyristors. To meet these demands we have developed a comprehensive range of thyristors optimised for medium voltage applications. As voltages increase, so do switching losses and turn-
We recognise the importance of reliability in these large, capital intensive applications and as a result we subject these parts to extended levels of both routine and type testing to ensure that your investment gives years of trouble free service.
Medium Voltage Thyristors
Introducing a new product range in our portfolio. Devices are available up to a voltage of 2800V. They exhibit very fast turn-
IXYS UK Westcode Ltd. are at the forefront of solid state pulsed power technology, offering custom solutions to complex pulsed power problems. Pulse thyristors are, in essence, optimised Gate Turn-
Devices with voltage ratings to 2.5kV, pulsed currents to 150kA peak and di/dt capabilities to over 30kA/microsecond are available. A selection of preferred parts is shown here, for other parts and technical support please contact the factory
