A Carrier-Based PWM Scheme for Neutral-Point Voltage Balancing in Three-Level Inverters
IEEE Transactions on Industry Applications, 2004A significant problem with neutral-point-clamped three-level inverters is the fluctuation in the neutral point voltage. In this paper, a capacitor voltage balancing technique for carrier-based three-level PWM is developed, with improved voltage control capability at high modulation index.

Two-stage interleaved three-level DC/AC converter with neutral point voltage balancing
2017 IEEE 3rd International Future Energy Electronics Conference and ECCE Asia (IFEEC 2017 - ECCE Asia), 2017This paper proposes a two-stage three-level DC/AC converter, which consists a three-level inter-leaved dc/dc boost converter in the first stage, and a three-level neutral-point-clamped (NPC) inverter in the second stage. The boost converter regulates variable and/or wide-range dc source, then provides suitable and stable dc voltage to the NPC inverter.

Abstract In this paper, a simplified control technique is proposed to control capacitor voltages of three-phase Neutral-Point Clamped bi-directional rectifier based on the modified modulation index technique. The modified modulation index technique generates new position of the reference vector in the space vector hexagon keeping both capacitor ...

Ten-switch three-phase three-level inverter (TP-TLI) is receiving more attention owing to the reduced system cost compared to traditional TP-TLIs. However, it still faces serious neutral-point voltage (NPV) balance problems. This article proposes a novel
