A self-commutating switch SW, operated at duty cycle \(\delta\) is used to control the load voltage as shown in the figure.Under steady state operating conditions, the average voltage across the inductor and the capacitor respectively, are |
A. | \({V_L} = 0\) and \({V_C} = \frac{1}{{1 - \delta }}{V_{dc}}\) |
B. | \({V_L} = \frac{\delta }{2}{V_{dc}}\) and \({V_C} = \frac{1}{{1 - \delta }}{V_{dc}}\) |
C. | \({V_L} = 0\) and \({V_C} = \frac{\delta }{{1 - \delta }}{V_{dc}}\) |
D. | \({V_L} = \frac{\delta }{2}{V_{dc}}\) and \({V_C} = \frac{\delta }{{1 + \delta }}{V_{dc}}\) |
Answer» B. \({V_L} = \frac{\delta }{2}{V_{dc}}\) and \({V_C} = \frac{1}{{1 - \delta }}{V_{dc}}\) | |
