b Explanation: The device only starts to conduct when the forward anode to cathode voltage exceeds the applied gate to cathode voltage.
b
Explanation: The device only starts to conduct when the forward anode to cathode
voltage exceeds the applied gate to cathode voltage.
c Explanation: PUT is Programmable Unijunction Transistor which is a p-n-p-n device just like the SCR with its gate connected to the n-type material.

a Explanation: DRF = 1-S.E Therefore 0.1 = (1-6000/1000Ns) = (1-1000/200Np) Ns = 6.6 = 7(say) Np = 5.5 = 6(say)
a
Explanation: DRF = 1-S.E
Therefore
0.1 = (1-6000/1000Ns) = (1-1000/200Np)
Ns = 6.6 = 7(say)
Np = 5.5 = 6(say)
a Explanation: The SCR with lower leakage current block more voltage.

Explanation: The SCR with lower leakage current block more voltage.
b Explanation: For uniform distribution of voltage across series connected SCRs, a resistor of value R in parallel with each series connected SCR.
b
Explanation: For uniform distribution of voltage across series connected SCRs, a resistor
of value R in parallel with each series connected SCR.
Answer: b Explanation: DRF = 1 – String efficiency String Efficiency = Rating of the whole string/(rating of one SCR x number of SCRs) Extra SCR will reduce the string efficiency which in turn increase the DRF
Answer: b
Explanation:
DRF = 1 – String efficiency
String Efficiency = Rating of the whole string/(rating of one SCR x number of SCRs)
Extra SCR will reduce the string efficiency which in turn increase the DRF
c Explanation: Unlike the other devices the SUS only turns-on for a fixed value of anode to cathode voltage.
