Reciprocity-transposition-based sinusoidal pulsewidth modulation for diode-clamped multilevel converters [PDF]
IEEE Transactions on Industrial Electronics, 2002 Modulation strategies for multilevel inverters have typically focused on synthesizing a desired set of three phase sinusoidal voltage waveforms using a fixed number of DC voltage levels. This results in the average current injection and hence the net power drawn from the multiple DC bus terminals to be unmatched and time varying.
