The steady state capacitor current of a conventional DC-DC buck converter, working in CCM, is shown in one switching cycle. If the input voltage is 30 V, the value of the inductor used, in mH, is ________ (round off to one decimal place).
Explanation:
Input voltage, 
In DC-DC buck converters, during conduction (ON) of switch, i.e,
from 0 to 
, 
(capacitor current) increases.
when switch is off, i.e from to 
decreases.
from wave form, 
μsec
Slope of 
slope of 
Also, 
(as Load current is constant)
When switch is ON :
