Question
A self commutating switch SW, operated at duty cycle 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

Correct answer
(A) V_L = 0 and V_C = (1)/(1-δ) V_(dc)
Solution
In steady state, the average voltage across an inductor over a full cycle is zero () due to the inductor volt-second balance principle. The circuit shown is a boost converter. For a boost converter, the relationship between the output capacitor voltage and the input DC voltage is given by . Therefore, the correct option is and .
