A Simplified PWM Strategy for a Neutral-Point-Clamped (NPC) Three-Level Converter With Unbalanced DC Links

IEEE Transactions on Power Electronics, 2016
A simplified pulse width modulation (PWM) strategy for a neutral-point-clamped three-level converter with unbalanced dc links is proposed in this paper to achieve high-quality line-to-line output voltages and to maximize the linear modulation range. The simplified strategy takes the direct output voltage modulation by calculating the special solutions ...

A New Three-Level Active Neutral-Point-Clamped (A-NPC) Multilevel Converter Topology

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
This paper proposes a new three-level active neutral-point-clamped (A-NPC) converter topology. The classic three-level A-NPC converter's phase-leg (per-phase) comprises the four line-frequency (LF) and two full-cycle-switched high-frequency (HF) pulse-width-modulation (PWM) power switches such as the insulated-gate bipolar transistors (IGBTs).
