Question
In the given rectifier, the delay angle of the thyristor measured from the positive going zero crossing of is . If the input voltage is V, the average voltage across (in Volt) under steady-state is _______.
Correct answer
61 to 62
Solution
The circuit is a single-phase bridge rectifier with one thyristor () and three diodes ().
1.During the positive half-cycle of , and can conduct. is triggered at . The output voltage for .
2.During the negative half-cycle of , and conduct automatically as they are diodes. The output voltage for .
The average output voltage is calculated as:Given V and :The value is approximately 61.53 V, which falls within the range 61 to 62.Continue learning with Success Tracker
