A commutating rectifier consists of commutator driven by___________?
Correct answer: B. a synchronous motor
- A. an induction motor
- B. a synchronous motor
- C. a D.C. series motor
- D. a D.C. shunt motor
Explanation
A commutating rectifier uses a mechanically driven commutator to perform rectification, and a synchronous motor provides the required constant-speed drive. An induction motor would not maintain the same precise speed under changing load.
