Advantages and disadvantages of Gate turn OFF thyristor (GTO)
There are some advantages of gate turn OFF thyristor (GTO) are given below,
- The gate turn OFF thyristor (GTO) has more di/dt ratings at turn ON.
- It has faster turn OFF permitting high switching frequencies.
- The communication circuit is not required, hence it reduced size, weight and cost.
- It has high efficiency.
- It has high capability of blocking voltage.
There are some disadvantages of gate turn OFF thyristor (GTO) are given below,
- In a gate turn OFF thyristor (GTO), ON state voltage drop and the associated loss is more.
- Gate drive circuit losses are more.
- In a gate turn OFF thyristor (GTO), magnitude of latching and holding current is more.
- Triggering gate current is higher as compared to the current required for a conventional SCR.
