Title: trigger and stop thryistor
Post by: hgul on August 26th, 2019, 01:52 AM
Hi I want make 8xa circuit with my friend. but we couldnt understnad that after trigger scr how can it be stop and trigger again. because you know after trigger scr it works continously .but in circuit we must generete pulse. on -off. Also why meyer used ecr thrystor c38m. not any mosfet.
 thanks:)
or my question is wrong :(

"But remember though that once a Thyristor starts to conduct it continues to conduct even with no Gate signal, until the Anode current decreases below the devices holding current, (IH) and below this value it automatically turns-“OFF”. Then unlike bipolar transistors and FET’s, thyristors cannot be used for amplification or controlled switching."

So you need to get the gate current lower enough.It seems you can find SCRs sensitive enough to react to light even, so you got many options
