This demo model shows the simulation of a grid-connected NPC inverter in closed current loop using SVPWM (Space-Vector PWM) and a neutral-point balancing technique. It provides an explanation of the typical workflow of the PLECS Embedded Coder, using Texas Instruments (TI) C2000 MCUs. Combined with. . Abstract— This paper presents a closed-loop control scheme for the three-level three-phase neutral-point-clamped dc-ac converter using the optimized nearest-three virtual-space-vector pulsewidth modulation, a modulation that produces a low output voltage distortion with a significant reduction of. . The three-level neutral-point-clamped (NPC) inverter is particularly well-suited for medium-voltage, high-power applications due to its lower line voltage Total Harmonic Distortion (THD), its ability to deliver twice the rated power output, and its reduced electromagnetic interference (EMI) [2, 3]. Advanced theoretical considerations are not covered.
