For the switching converter shown in the following figure,

For the switching converter shown in the following figure, assume steady-state operation. Also assume that the components are ideal, the inductor current is always positive and continuous and switching period is T₅. If the voltage V_L is as shown, the duty cycle of the switch S is ________.

V_S = 15V
V₀ = V_S = - 45
V₀ = V_V + 45
= (15 + 45) V = 60V

Now, V₀ =	V_S	= %
	1 - D

∴ 60 =	15	= %
	1 - D

∴ 60(1 – D) = 15

∴ 1 - D =	1
	4

∴ D =	3	= 0.75
	4
