In single phase RLE load, calculate the angle at which conduction starts using the data: (Vs)=14sin(Ωt), f=50 Hz, E=10 V.(a) 45.58°(b) 46.26°(c) 47.26°(d) 49.56°I had been asked this question during an interview for a job.The question is from Solid-State Switching Circuits in division Introduction to Solid-State Switching Circuits of Electric Drives

Answer»

Correct ANSWER is (a) 45.58°

Explanation: The ANGLE at which conduction STARTS when Vmsin(θ)=E. The conduction will remain from ϴ to π-θ. Θ=SIN-(E÷Vm)=sin-(.71)=45.58°.
