Abstract
A power electronics switching system has a power converter including switching elements respectively disposed in parallel paths. The system also has a controller that outputs switching commands for the switching elements derived from carrier waveforms and reference waveforms corresponding to the switching elements, and generates a shape for one of the carrier waveforms according to a difference in magnitudes between the reference waveforms such that the shape is of a first type responsive to the difference being greater than a first threshold and is of a second type different than the first type responsive to the difference being less than a second threshold.
