what is firing angle for thyristors.how can i found the firing circuit for thyristors?

Answer 1

The term firing angle is normally used when an AC signal is applied to the anode and the gate voltage is applied at different times in the AC signal.
Pulses are applied to the gate by using either UJTs ( Unijunction transistors or DIACs that discharge a capacitor at the right moment.

Answer 2

A thyristor is a PNPN gadget additionally commonplace as SCR or silicon controlled rectifier. it is VI charecteristics is like an S with long linear head on a pointy bent. usually that's utilized in motor administration. you're able to make it function interior the linear region by using using the luxurious inputs to the P N and P junctions. You connect the enter voltage to the P junction and the administration voltage from the armature to the N junction and make the thyristor function interior the linear region. If for any reason the armature voltage decreases then the motor stops. the two the N or P junction may well be used for various administration movements jointly or singly finding on the style of reference voltages needed for the specific administration action.

Answer 3

It depends on the power proportion of the circuit to be fired.
