Biel, Switzerland-based IXYS Corp.'s wholly owned U.K. subsidiary, Westcode Semiconductors Ltd., has launched a new 6.5 kV phase control thyristor for megawatt scale applications.
The new device is optimized for low forward conduction loss, has a nominal RMS current rating of 1695 A and features a surge current rating of 10.5 kA. The device is encapsulated in a 1.85-inch pole-face, hermetic-pressure contact package using Westcode's alloy-free process.
The new phase control device is optimized for very low on-state voltage – when compared to similar devices in the same voltage class – with a forward volt drop of 2.0 volts at 1000 A. This new thyristor is part of IXYS' global strategy of introducing power semiconductors that improve the energy efficiency of electrical power systems, according to the company.
Low conduction loss makes the device ideal for line frequency applications, such as front-end rectification, as well as all controlled rectifier applications up to a few hundred hertz.
Other applications for which the device is ideally suited include DC drives, load commutated inverters and excitation equipment, power and motor control for electrical trains, high-power generators, uninterruptible power supplies and renewable energy applications, including solar power and wind turbine generators.
The devices are available in two voltage classes and with two package options.
