Fault-Tolerant Control Strategy for Neutral-Point-Clamped Three-Level Inverter
Journal of Control Science and Engineering, 2018 A fault-tolerant control technique is discussed for the Neutral-Point-Clamped (NPC) three-level inverter, which ensures that the NPC inverter operates normally even under device failures. A two-level leg is added to the NPC inverter; when the device open
