engineering recuitment GATE EE 2023-24 Test Series Power Electronics and Drives Phase Controlled Rectifiers Effect of Source Impedance on Converters
A 3-phase full converter bridge has an RLE load, the source has definite inductance causing overlap and SCR are ideal. It has an overlap angle μ of 15° at the minimum firing angle ∝. The current remain constant in the complete range of firing angles. The range of firing angle would be.
