For bidirectional operation of converters____________?
Correct answer: A. A parallel combination of controllable switch and a diode is used
- A. A parallel combination of controllable switch and a diode is used
- B. A parallel combination of controllable switch and capacitor is used
- C. A series combination of controllable switch and a diode is used
- D. A series combination of controllable switch and a capacitor is used
Explanation
Bidirectional current flow is obtained by placing a controllable switch and a diode in parallel with opposite current directions. The switch conducts one way while the antiparallel diode provides the reverse-current path.
