This means that the envelope of the output waveform is distorted.
This creates a line-to-line output waveform that has six steps.
In either case, the output waveforms are phase shifted to obtain a 12-step waveform.
The output waveform is heavily distorted unless careful measures are taken to prevent this.
This gives stepped output waveforms instead of pulsed signals.
The output waveform is therefore distorted, but not clipped.
The output waveforms are therefore made up of discrete values, producing fast transitions rather than smooth ones.
The desired quality of the current output waveform determines which modulation technique needs to be selected for a given application.
Any undesirable odd (N-1) intrinsic harmonics from the output waveform can be eliminated.
This particular feature allows for smaller filtering components when trying to obtain a higher quality output waveform.
