Thyratrons were used for industrial control before the discovery of thyristors device but now they have been replaced by the thyristors in nowadays. They both are three-terminal devices still the construction of gate terminal are different form. Now let check it out the difference between them to know more about that.
Difference between thyristor and thyratron :
- Thyristor is a current controlled device while thyratron is a voltage-controlled device.
- Thyristor is light in weight and require less space, thyratron heavy and requires more space.
- Thyristor is more reliable whereas thyratron is not reliable.
- Thyristor is higher Turn-ON and Turn-OFF time and smaller Turn-ON and Turn-OFF time in case of thyratron device.
- A thyristor is more accurate comparison to the thyratron.
- A thyratron is costlier compared to the thyristor.
- Thyristor needs only one low power supply and control signal to perform the operation while Thyratron needs too much large power supply between anode and cathode.
- The life of thyristor is greater than to thyratron.
- Internal losses are more in the case of thyratron as compare to the thyristor device.
- The thyristor is a more accurate comparison to the thyratron.
- Thyratron takes a long time in ionizing and deionizing, therefore, is unsuitable for higher frequency but thyristor can operate a wide range of frequencies.
