FPGA Implementation of Multilevel Space Vector PWM Algorithms

International Journal of Engineering and Technology, 2009
Multilevel converters can meet the increasing demand of power rating and power quality associated with reduced harmonic distortion and lower electromagnetic interface. With the increase in number of levels, it is necessary to control more and more switches in parallel. Field programmable gate arrays (FPGAs), with their concurrent processing capability,
