Explanation:
A three-phase half-wave diode rectifier consists of three diodes connected to a three-phase AC supply. Each diode conducts in one of the three phases of the AC supply and blocks the current flow in the other two phases.
Working:
During each phase of the AC supply, the corresponding diode becomes forward-biased and conducts current through it. Let's understand the working of a three-phase half-wave diode rectifier using the following points:
1. Phase 1:
During the first phase of the AC supply, diode D1 conducts and allows current to flow through it. The other two diodes, D2 and D3, are reverse-biased and block the current.
2. Phase 2:
During the second phase of the AC supply, diode D2 conducts and allows current to flow through it. Diodes D1 and D3 are reverse-biased.
3. Phase 3:
During the third phase of the AC supply, diode D3 conducts and allows current to flow through it. Diodes D1 and D2 are reverse-biased.
Conduction Angle:
The conduction angle is the duration for which each diode conducts during one cycle of the AC supply. In a three-phase half-wave diode rectifier, each diode conducts for a conduction angle of 120 degrees.
During each phase, the diode conducts for 120 degrees, which is one-third of the total time period of 360 degrees. This ensures that all three phases of the AC supply are rectified and converted into DC.
Therefore, the correct answer is option 'B' - 120 degrees.
