Dual Flying Capacitor Active-Neutral-Point-Clamped Multilevel Converter
IEEE Transactions on Power Electronics, 2016Hybrid multilevel converters combine features of conventional multilevel topologies to provide an acceptable tradeoff between the advantages and disadvantages of these converters. For many industrial applications, common dc link is a requirement that limits the choice of topologies to neutral point clamped (NPC) and flying capacitor multicell (FCM ...

Four-Level Hybrid Neutral Point Clamped Converters
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021In terms of low-voltage ( 10 kW) industry applications, power converters without any flying capacitors are preferred to ensure high efficiency, high power density, and light weight. As for these requirements, this article proposes a four-level hybrid neutral point clamped (4L-HNPC) converter and a four-level hybrid active neutral point clamped (4L ...

Average Neutral Point Current Control Strategy in Neutral-Point-Clamped Converters
2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia), 2021A control strategy for regulating the average neutral point (NP) current in neutral-point-clamped (NPC) converters is proposed in this paper. Previously presented strategies in the literature control the instantaneous NP current. However, the instantaneous maximum NP current profile is time-varying, which results in difficulties to regulate the average

Active Neutral-Point-Clamped Multilevel Converters
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006This paper proposes a multilevel power conversion concept based on the combination of neutral-point-clamped (NPC) and floating capacitor converters. In the proposed scheme, the voltage balancing across the floating capacitors is achieved by using a proper selection of redundant switching states, and the neutral-point voltage is controlled by the ...

Design Considerations for Neutral Point Clamped Converters
IEEE International Conference on Electric Machines and Drives, 2005., 2005Despite the growing proliferation of three level converters, practical design guidelines for these systems are not readily available. This paper describes such design guidelines for the construction and control of three level converters. Loss equations that assist in thermal design and device sizing are provided along with current estimates for sizing ...

Hybrid Modulation Technique for the Neutral-Point-Clamped Converter
2007 Compatibility in Power Electronics, 2007This paper presents a hybrid modulation technique for the three-level neutral-point-clamped converter. A modulation strategy that was presented previously is able to remove completely the low frequency voltage oscillations that appear on the neutral point for some operation conditions.
