Abstract

A multilevel variable speed induction motor drive scheme using 18-sided polygon with very dense voltage space vector structure (SVS) is proposed in this paper. The SVS consists of 54 concentric 18-sided polygons generated by superposition of 5-level primary hexagonal SVS of radius VDC and 5-level secondary hexagonal SVS of radius 0.379VDC. Dense voltage space vector structure facilitates generation of reference by nearest vector switching in 18-sided polygon with least switching in the inverter pole voltages. Simulation and experimental results of the proposed drive scheme are presented to prove effectiveness of the drive scheme.
