Question
Consider the boost converter shown. Switch is operating at with a duty cycle of . Assume the diode and switch to be ideal. Under steady-state condition, the average resistance as seen by the source is ______ . (Round off to 2 decimal places.)
Correct answer
1.55 to 1.65
Solution
For an ideal boost converter in steady state:
1.The output voltage is related to the source voltage by:
2.Assuming a lossless converter, the input power equals the output power:
3.The input resistance as seen by the source is:
