Research on the Fault-Tolerant Control Algorithm of SVPWM for NPC Three-Level Inverters

Abstract:

This paper mainly introduces fault-tolerant technology of three-level NPC inverters. For the three-level inverter topology and control characteristics, we use space vector (SVPWM) algorithm for modulation. when a short circuit fault in the inverter device,we use redundant space voltage vectors, and get control algorithm of redundant. Using MATLAB/Simulink software, a simulation model is analyzed, and the results demonstrate the feasibility of the method.
