Circuit Turn Off Time for Main SCR in Chopper Solution

Follow our step by step solution on how to calculate Circuit Turn Off Time for Main SCR in Chopper?

FIRST Step Consider the formula

T c = \frac{1}{ω o} \cdot (π - 2 \cdot θ 1)

Next Step Substitute values of Variables

∴

T c = \frac{1}{7.67rad/s} \cdot (π - 2 \cdot 0.8°)

Next Step Substitute values of Constants

∴

T c = \frac{1}{7.67rad/s} \cdot (3.1416 - 2 \cdot 0.8°)

Next Step Convert Units

∴

T c = \frac{1}{7.67rad/s} \cdot (3.1416 - 2 \cdot 0.014rad)

Next Step Prepare to Evaluate

∴

T c = \frac{1}{7.67} \cdot (3.1416 - 2 \cdot 0.014)

Next Step Evaluate

∴

T c = 0.405954026800246s

LAST Step Rounding Answer

∴

T c = 0.406s
