特性 Features

Medium voltage applications place additional demands on phase controlled thyristors. To meet these demands we have developed a comprehensive range of thyristorsoptimised for medium voltage applications. As voltages increase, so do switching losses and turn-off time to a point where they become significant in line frequencyapplications. Our patented distributed gate architecture ensures excellent switching performance over a wide range of voltage, current and di/dt. Device lifetime is alsoengineered to achieve an optimum balance between conduction losses, commutation losses and turn-off time to give maximum power handling from line frequency to400Hz. This also gives significant benefits when series or parallel connection of devices is required. Medium voltage thyristors are available from 3.2kV up to 6.5kV withsilicon diameters from 38mm to 100mm making them particularly suitable for high power converters such as medium voltage DC drives, medium voltage soft starts and utilityapplications such as HVDC, static VAr compensators, excitation and transfer switches.
