Abstract
A Space Vector based Pulse Width Modulation (SVPWM) scheme for a 5-level inverter is presented. Sector identification is carried out using an approach based on fractal concept. To represent the space vectors, 60° coordinate system is used. The use of 60° coordinate system avoids fractal arithmetic compared to Cartesian coordinate system, and increases speed of computation. No look up tables are used to generate sectors and switching vectors. The scheme also works in over modulation region. Experimental results for a 5-level inverter using induction motor in open-end winding configuration are presented to validate the scheme.
