Popis:	A number of voltage-control schemes in 3-phase bridge inverters are investigated. These control schemes are applied to dual 3-phase cascaded bridge inverters with fifth- and seventh-harmonic neutralization to realize pulse-width and amplitude controlled waveforms. kVA ratings of filter components are calculated to realize a total harmonic distortion of 5% in the output waveform. The control scheme with two pulses per half cycle spaced 60° apart in individual inverters gives the lowest total harmonic distortion and requires the lowest filter kVA rating. The theoretical results are experimentally verified and are in closo agreement.
