Thyristors for renewable energy applications

The N1479NC24R and N1479NC30R are phase control thyristor with voltage grades at 2.4 kV and 3 kV respectively. The thyristor is specially designed in a package suitable for rotating applications.

The thyristor rated at 3000 V, is based on IXYS UK’s world class all diffused silicon process with the silicon slice fused to a metal disc for optimum thermal and mechanical durability. The device has average current rating of 1436 A at a heat sink temperature of 55⁰C and is suitable for line frequency applications up to 400 Hz. The fully hermetic package has been especially designed to withstand movement of the silicon die when rotated tangential to the plane of the electrodes. The new package design is suitable for applications with acceleration of up to 620 metres per second squared, when the device is mounted with the anode electrode facing the centre of rotation.
