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)
