Six-step operation of an inverter gives

  • A.the smallest fundamental output with the best waveform quality
  • B.a perfectly sinusoidal output with no harmonics at all
  • C.no output voltage of any useful magnitude
  • D.the largest fundamental output but poor waveform quality

Answer: D

Each device conducts for a hundred and eighty degrees, which extracts the most from the link but leaves fifth and seventh harmonics in the output. Drives use it at the top of the speed range where voltage matters more than waveform.
