Question
In the circuit shown all elements are ideal and the switch is operated at and duty ratio. The capacitor is large enough so that the ripple across it is negligible and at steady state acquires a voltage as shown. The peak current in amperes drawn from the DC source is __________. (Give the answer up to one decimal place.)
Correct answer
39 to 41
Solution
The given circuit is a Buck-Boost converter.
Given: , , , , .
Given: , , , , .
1.Output Voltage: .
2.Average Inductor Current: .
3.Inductor Current Ripple: .
4.Peak Inductor Current: .
Since the source current is equal to the inductor current when the switch is closed, the peak current drawn from the source is the peak inductor current, which is .Continue learning with Success Tracker
