For commutation in three phase PAC, normally balanced three phase voltages VR, VY and VB are connected to the three legs of the converter via______________?
Correct answer: A. Three inductances
- A. Three inductances
- B. Three capacitances
- C. Three resistance
- D. Three transistors
Explanation
The three AC source phases are connected through source inductances, which limit current rise and provide the overlap needed during commutation. Resistors, capacitors, and transistors do not serve this normal commutation function.
