Thyristors for commutation of current impulse with extremely high amplitude

There was developed a new generation of silicon pulse thyristors adapted for commutation of current impulses with extremely high amplitude, 100–1000 μs width. A variety of improvements was done in the layers of silicon structure, topology, and technology of anode and cathode contact generation. It is experimentally proved that commutation of current impulse with amplitude up to 250 kA and 500 μm width by thyristor with 100 mm silicon element is possible.
