Abstract

In this paper, a drive scheme generating 24-sided polygonal voltage space vector structure using an inverter topology with single DC source is proposed. A 24-sided structure eliminates dominant low-order phase voltage harmonics including and up to seventeenth and nineteenth orders throughout the speed range including step operation. The power circuit has a two-level inverter and two low voltage cascaded H-bridge cells fed with capacitors. The linear modulation range is extended to 99.42% of the base speed with such a polygonal structure. A reduced PWM switching sequence resulting in minimum pole voltage transitions for the two-level inverter and shifting relatively higher frequency operation to low voltage H-Bridge inverters feature the drive scheme for controlling losses.
