Q:

Calculate the PIV for the Full-wave bridge rectifier if the peak value of the supply voltage is 50.

A) 72.5 V B) 72.8 V
C) 70.7 V D) 76.1 V
 
Answer & Explanation Answer: C) 70.7 V

Explanation: The peak inverse voltage for the Full-wave bridge rectifier is Vm = ?2×230=70.7 V. The peak inverse is the maximum negative voltage across the thyristor.

Q:

Calculate the maximum frequency for ASCI using the data: R=1 k?, C=1 ?F.

A) 250 Hz B) 280 Hz
C) 300 Hz D) 320 Hz
 
Answer & Explanation Answer: A) 250 Hz

Explanation: The minimum time period for ASCI is a 4×R×C=4×1×1×.001=4 msec. The total time is the sum of charging and discharging time. The maximum frequency is 1÷f=250 Hz.
