The output current in PWM DC - DC converters is equal to___________?
Correct answer: C. Either A. or B.
- A. Average value of the output inductor current
- B. Product of an average inductor current and a function of duty ratio
- C. Either A. or B.
- D. None of these
Explanation
In a buck converter, output current equals the average inductor current, while in other PWM converters it may be a duty-ratio-weighted value such as [?] (1-D) times the inductor current. Thus, depending on the converter topology, either relationship can apply.
