COMPARISON BETWEEN THYRISTORS AND THYRATRONS.

sl.no THYRATRONS THYRISTORS
1. Requires a large anode to cathode voltage and a seperate filament supply to turn ON Needs only one main supply and a control signal to turn ON
2. Takes long time for Ionising and De-Ionising Requires only short time
3. Not suitable for higher Frequency Range Operate over large Frequency Range
4. Turn ON and OFF time is larger Quick Turn ON and OFF time
5. smaller Life time improved lifetime than that of thyratrons
6. Less Reliable More Reliable
7. Large internal Losses takes place Lower than Thyratrons
8. Bulky in size Reduced Size and weight
9. Voltage Controlled Device Current Controlled Device
