Question
In the DC-DC converter shown in the figure, the current through the inductor is continuous. The switching frequency is Hz. The voltage () across the load is assumed to be constant and ripple free. The peak inductor current in amperes is _________ (rounded off to the nearest integer).
Correct answer
13 to 13
Solution
1.Identify the converter type: Since V and V, it is a Boost converter.
2.Calculate the duty cycle (): For a Boost converter, .
3.Calculate the average output current (): A.
4.Calculate the average inductor current (): A.
5.Calculate the inductor current ripple (): A.
6.Calculate the peak inductor current (): A.
