For power output higher than 15 kW, the suitable rectifier is________________?
Correct answer: D. Only (b) and (c)
- A. Single phase
- B. 3 phase
- C. Poly phase
- D. Only (b) and (c)
Explanation
For outputs above about 15 kW, three-phase or polyphase rectifiers are preferred because they provide smoother DC and lower ripple current than single-phase rectifiers. Since three-phase is a type of polyphase system, both options b and c apply.
