Design a Cuk converter that has an input of 25V and the output of -30V. The load is 60W. Specify the duty ratio, switching frequency, inductor values and capacitor values. The maximum change in inductor currents must be 20 percent of the average currents. The ripple voltage across capacitor C1 must be less than 5 percent, and the output ripple voltage must be less than 1 percent.
A step down converter is operated with a duty cycle of k = 0.75. The input voltage is Vs = 20V, and the
load is: L = 5mH, R = 1502. The minimum inductor current is I₁ = 0.1A. The maximum inductor
current is:
Select one:
a. 1.9 A
b. None of these
OC. 0.9 A
O d. 1.1 A
Oe. 2 A
Boost Converter Design
A boost converter is required to have an output voltage of 8 V and supply a load current
of 1 A. The input voltage varies from 2.7 to 4.2 V. A control circuit adjusts the duty ratio
to keep the output voltage constant. Select the switching frequency. Determine a value for
the inductor such that the variation in inductor current is no more than 40 percent of
the average inductor current for all operating conditions. Determine a value of an ideal
capacitor such that the output voltage ripple is no more than 2 percent. Determine the
maximum capacitor equivalent series resistance for a 2 percent ripple.
