Thyristor Circuit. These terminals are anode cathode and gate. These two electrodes are called the anode and cathode.
Basic circuit for obtaining v i characteristic. These two electrodes are called the anode and cathode. Whenever a gate receives a triggering current then it starts conducting until the voltage across the thyistor device is under forward bias.
A thyristor is a four layer device with alternating p type and n type semiconductors p n p n.
In its most basic form a thyristor has three terminals. So it acts as a bistable switch under this condition. All portions of the circuit except for the rc network are shaded for de emphasis. Basic circuit for obtaining v i characteristic.
