Power ElectronicsCommutation Overlap

Increasing commutation overlap in a line-commutated converter generally causes the average DC output voltage to?

  • ADecrease
  • BIncrease without limit
  • CRemain exactly unchanged
  • DBecome equal to peak line voltage
Report an error
Correct Answer: A. Decrease
Explanation: Commutation overlap introduces an additional voltage drop/loss of average output voltage.
Reference: Standard power electronics: commutation overlap
