Patent GB-2059193-A (GB)
Title: A switching device
IPC: H03K17/52
Filed: 1980-09-08
Abstract: It has not hitherto been possible to operate two thyratrons in parallel at very high switching frequencies. This is because no two thyratrons have identical characteristics so they would fire at different times. This problem is solved by triggering the two parallel thyratrons 12, 13 through a line 15 including the secondary of a transformer 18. When one thyratron fires the resulting current passes through the primary of the transformer thereby inducing a further or stronger impulse on line 15. This ensures that the firing of one thyristor will be simultaneous with or will be rapidly followed by the firing of the other. <IMAGE>
