2. If SCR-T2 is not conducting even with the gate pulses what will be the effect on output voltage?
3. An isolation transformer with turns ratio 2:1 is used instead of 1:1. What will be the relation between the source current (IS) and load current (I0).
4. Maximum voltage (Vmax) across SCR at firing angle 30 degree and 150 degree will be (Vm is the peak source voltage)
5. What should be the relation between firing angle (α), extinction angle (β) and conduction angle (γ) for non-zero output current?
