I-V characteristics of thyristor
I-V characteristics of thyristor consist three modes of operation
1- Reverse blocking mode
2- Forward blocking mode
3- Forward conduction mode
Turn on method of thyristor
With anode positive with respect to cathode,a thyristor can be turn on by any one of the following techniques:
1-forward voltage triggering
2-gate triggering
3-dv/dt triggering
4-temperature triggering
5-light triggering
