The circuit shown below has C = 20 μF and L = 5 μH. Initial voltage across the capacitor is Vs = 230 V. The load current is constant at 300 A . Let ‘A’ be the conduction time period of the auxiliary thyristor and ‘B’ is the circuit turn off time of the main thyristor. Than A + B will be _________.
  • a)
    11.6 μsec
  • b)
    31.4 μsec
  • c)
    25.6 μsec
  • d)
    42.6 μsec

Verified Answer
The circuit shown below has C = 20 μF and L = 5 μH. Initial voltage a...
The above circuit is class 'B' commutation.
So, the conduction time of auxiliary thyristor is =
A = 31.4 \musec
The peak value of resonant current,
Voltage across the main thyristor, when it gets turned off will be
Circuit turn off time for main thyristor is
So, A + B = 31.4 + 11.62
=
