A Carrier-Based PWM Scheme for Neutral-Point Voltage Balancing in Three-Level Inverters

IEEE Transactions on Industry Applications, 2004
A 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), 2017
This 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.

Capacitor voltage balancing in neutral-point clamped rectifier using modified modulation index technique

Computers & Electrical Engineering, 2018
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 ...
