Abstract

Continuity operating within isolated telecommunication sites is an important challenge. In this paper, a new fault tolerant SVM (Space Vector Modulation) strategy for 3 level NPC (Neutral point Clamped) inverter used in isolated telecommunication sites is proposed. It inssures a continuous operation of the laod after a breakdown of an inverter power switch. Simulation results prove the good performances of the proposed srategy.
