Solution 1
It seems like your question is incomplete. However, I can provide a general answer based on the information given.
In a single-phase fully controlled bridge rectifier, each thyristor conducts for a certain period depending on the firing angle (α). The conduction period for each thyristor is 180 degrees (π radians) in a full cycle of 360 degrees (2π radians).
The conduction starts at the firing angle (α) and ends at (π+α). So, each thyristor conducts for (π+α) - α = π radians or 180 degrees.
Please provide more specific details if you need a more specific answer.
Solution 2
It seems like your question is incomplete. However, I can tell you that in a single-phase fully controlled bridge rectifier, each thyristor will conduct for 180 degrees of the input cycle. The conduction starts at an angle α (alpha) after the positive zero crossing for the first pair of thyristors and at an angle α (alpha) after the negative zero crossing for the second pair of thyristors. Therefore, the conduction angle for each thyristor is (180 - α) or (π - α) in radians.
