A combination of synchronized leading edge and trailing edge modulation has also been used to control a____________?
Correct answer: C. Both A. and B.
- A. Boost single - phase power factor converter
- B. A buck dc - dc converter to reduce ripple in the intermediate dc bus capacitor
- C. Both A. and B.
- D. None f these
Explanation
Synchronized leading-edge and trailing-edge modulation can be applied to a boost single-phase power-factor converter and to a buck converter for reducing intermediate DC-bus capacitor ripple. Therefore both listed applications are valid.
