The carrier which are commonly used in constant - frequency PWM is______________?
Correct answer: D. All of these
- A. Sawtooth carrier
- B. Inverted sawtooth carrier
- C. Triangle carrier
- D. All of these
Explanation
Constant-frequency PWM can compare the reference with a triangular, sawtooth, or inverted-sawtooth carrier. The carrier shape changes the switching pattern, but all listed forms can be used.
