From (4.2) the net change in the inductor current during the OFF time of the switch is

(4.4)

According to the inherent property of the inductor, the net current in the inductor during the complete cycle should be zero. Thus,

(4.5)

From (4.3) and (4.4):

(4.6)

The duty cycle of the power switch is defined as the effective ON time of the switch. So the duty cycle of switch is defined as:

(4.7)

From (4.6) and (4.7), for the buck converter (step down chopper):

(4.8)

From the equations, it is obvious that duty cycle (D) is always less than 1 and the maximum value is 1 (Switch is ON for 100 % of the time).

Thus from (4.8) it is clear that
