Phase control thyristors

10 June 2015 Power Electronics / Power Management

IXYS introduced a new 3,6 kV pressure contact phase control thyristor with increased power density. The improved design offers up to 52% increase in average current rating over the established designs while retaining the overall package footprint. Typical applications include soft starters, DC drives and all controlled rectifier applications requiring devices in this power rating.

This improvement in performance is achieved by maximising the die size and an improved package design. The new silicon die is alloyed to a metal disc and encapsulated in a fully hermetic ceramic package. Overall the new mechanical design presents reduced thermal resistance and the die has enhanced electrical performance.

The new 56 mm die device has an average current rating of 1725 A and the package has a 50 mm electrode contact diameter, with an industry standard overall diameter of 74 mm. The parts – N1314NC360 and N1478NC300 – will ultimately replace two older designs based on 53 mm dice, offering a respective increase in average current of 31% and 17%.

The new thyristors remain mechanically compatible with the old designs and can be used in the same mechanical systems. They are also an alternative to the current 50 mm die design offering the potential of 52% more current rating in the same mechanical footprint, as long as the cooling and clamping systems are appropriately scaled to accommodate the larger die area.

The new device is available in an industry standard 26 mm thick package and two voltage grades – N1725MC320 (Vdrm/Vrrm 3200 V) and N1725MC360 (Vdrm/Vrrm 3600 V). A version of this device optimised for series operation in medium-voltage applications will also be available.
