(i)elimination of commutating components in forced commutation,resulting in reduction in cost,weight and volume
(ii)faster turn-off permitting high switching frequencies
(iii)improved efficiency of converters
(iv)reduction in acoustic and electromagnetic noise due to elimination of communication chokes
(v)high blocking voltage and large current capability.
In low-power application,
GTOs have the following advantages over BJTs:
1.Higher blocking voltage capability.
2.High ratio of peak controllable current to average current.
3.High ratio of peak surge current to average current,typically 10:1.
4.High on-state gain (anode current and gate current) typically 600
5. Pulsed gate signal of short duration.
under surge conditions,a GTO goes into deeper saturation due to regenerative action.On the other hand,a BJT tends to come out of saturation.
