title = "Discontinuous Pulse Width Modulation for Improving Reliability of NPC Inverter Operated at High Modulation Index",
abstract = "In a 3-level NPC inverter, the power devices and DC-link capacitors are considered the most reliability-critical components, and their wear-out failure is mainly caused by thermal loading due to power loss. It is found in a previous study that the Discontinuous Pulse Width Modulation reduces the power loss of the power devices and improves the reliability of power devices. However, it reduces the reliability of the DC-link capacitor, and thus the reliability of the NPC inverter. This paper proposes a DPWM method to improve the reliability of the NPC inverter by reducing the power losses of both the power devices and DC-link capacitors. The effectiveness of the proposed method is verified through simulations and experiments.",
