ABB DSA1208-30A semiconductor device

Description

Semiconductor devices have made dramatic progress in power handling during the last
decade. The today’s technology and production capabilities make it possible to produce
devices with high blocking voltage combined with very high current handling. Depending
on the design and the device structure also very high current rise rates in the range of up
to several tenth’s of kA/µs are possible. Especially for single pulse or medium pulse
repetition rates semiconductor devices are getting more and more competitive to
conventional technologies like Thyratrons, Ignitrons, Spark-Gaps and Mechanical
Switches. The main advantages are the reliability, lifetime and almost no maintenance of
the semiconductor switches if the characterization is done right. Main advantages like
longer life-time, environmental friendly (no mercury etc.) and flexible mounting position are
compensating the higher initial cost of a solid state design.

The type of semiconductor
used and the rating of the device are extremely important for a reliable operation and
need an in-depth know-how of the application and the switching device. ABB has
developed over the years a specific range of semiconductor devices and adapted
standard products which can fulfil the requirements for pulsed applications. Beside the
semiconductor devices, ABB is also in the position to supply complete custom made
ready-to-use solid state switch assemblies including clamping, triggering, cooling and with
application oriented testing. The presentation describes both, the loose semiconductor
components as well as some custom made solid state switches for single pulse or low
repetition rate pulsing.
