In a phase-shift control method, the phase shift between anode and grid voltages can be achieved by means of______________?
Correct answer: C. induction regulator
- A. shunt motor
- B. synchronous motor
- C. induction regulator
- D. synchronous generator
Explanation
An induction regulator can vary the phase of its output voltage relative to the supply voltage, providing the required phase shift between anode and grid voltages. Motors and generators do not directly provide this adjustable phase-shifting function.
