Switching characteristics during turn on

A positive  gate  pulse  between  gate and  cathodeis sufficient to turn  on a thyrisotr. In  this period  thyristor  changes its state from  forward  off blocking  state  to on state  and starts conduction. Time  is turn on time of a thyristor which  can be  divided into three  intervals.

a.Delay time (td)

b.Rise time (tr) and

c.Spread time ( ts)
