This work addresses the design and experimental validation of a three-level Neutral-Point Clamped (NPC) inverter. A Space-Vector Modulation (SVM) algorithm which simplifies the space-vector diagram of a three-level inverter so that it can be used with a two-level inverter is developed. The dwell times are calculated on the simplification process in the same way as for a conventional two-level SVM method. Experimental results that validate the SVM algorithm developed to control the three-level NPC are presented. The SVM algorithm is programmed on a Freescale DSP56F8037 development system.
