Question
Consider the buck-boost converter shown. Switch is operating at and duty-cycle. Assume diode and switch to be ideal. Under steady-state condition, the average current flowing through the inductor is ______ .
Correct answer
24 to 24
Solution
For an ideal buck-boost converter in steady state:
1.The output voltage magnitude is:
2.The average inductor current is the sum of the average input current and the average output current :
