Extreme high switch on capabilities of up to 20 kA / µs
Undoubtedly, our high di/dt pulse power switches are the perfect solution in situations where extremely fast switch-on is required. Because, our specially designed and treated thyristor elements enable switching speeds of up to 20kA per microsecond (µs). Furthermore, with parallel connection even higher di/dt values can be achieved. Given that in all our thyristor switches the required voltage level is achieved by connecting the right number of elements in series.
The maintenance-free thyratron replacement
High di/dt switches are often used as part of pulse forming networks, which are connected to loads such as magnetic forming equipment, plasma reactors, particle accelerator in atomic research and other applications. Because of their solid-state and maintenance-free design it makes them the ideal solution to replace the high maintenance thyratrons.
We combine specialized GCTs, gate drivers and control electronics to achieve high di/dt-pulses
