In a three phase voltage source inverters____________?
Correct answer: D. Amplitude, phase and frequency of voltages should always be controllable
- A. Only amplitude of voltage is controllable
- B. Only phase is controllable
- C. Both amplitude and phase is controllable
- D. Amplitude, phase and frequency of voltages should always be controllable
Explanation
A three-phase VSI can regulate the output voltage magnitude and establish its frequency and phase through the switching reference. Thus amplitude, phase and frequency are controllable quantities in inverter operation.
