Download Solution PDFAn SCR HWR is applied a Sine wave voltage. If its firing angle is 45°, what is the value of the maximum conduction angle possible if load is purely resistive in nature? Identify from the options given below.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConduction angle :
The number of degree’s in a half cycle for which SCR is turned ON, is known as Conduction angle (γT).
Single Phase Half Controlled Rectifier:
The firing angle α = 450
From the above waveform, conduction angle (γT) = π - α
= π – 450 = 1350Last updated on Jun 2, 2025
