Abstract

This   paper   investigates   the   power   losses   in semiconductors  for  a  three-phase,  three  level  neutral  point clamped  (3L-NPC)  inverter.  Analytical  expressions  for  the switching  and  conductor  losses  are  derived.  Three  different modulation   strategies   are   analyzed:   sinusoidal   modulation (SPWM);  sine  modulation  with  injection  of  the  third  harmonic (THIPWM);   carrier   based   space   vector   modulation   (CB-SVMPWM).  Based  on  these  strategies,  the  inverter  losses  are estimated   through   computational  simulation   under   different operating  conditions.  The  influence  of  these  strategies  on  the losses is also analyzed.
