Floating capacitor voltage regulation in diode clamped hybrid multilevel converters
2009 IEEE Electric Ship Technologies Symposium, 2009The family of hybrid topologies consisting primarily of a main Neutral Point Clamped (NPC) 3-phase inverter followed by one or more series connected H-Bridges in each output phase show promise in medium voltage applications requiring high power quality and minimal size and weight. Another distinct advantage of this topology is the ability to supply the

Diode-clamped multilevel converter topology for battery cells charging applications
2013 IEEE Energytech, 2013A new charger control strategy for optimum charging of individual battery cells is proposed. The charger can directly charge individual battery cells based on their state-of-charge (SOC) using multilevel converter topology. In multilevel converter, individual cells are connected in series on the DC side of the converter.

Modeling and control of a five-level Diode-Clamped Converter based StatCom
2009 IEEE International Conference on Industrial Technology, 2009This paper presents a state model of a three-phase, four-wire five-level Diode-Clamped Converter (DCC) employed in a Static Compensator (StatCom) for medium power applications. Two auxiliary circuits are used to equalize the voltages across the DC-bus capacitors. A detailed controller design procedure is presented.

A Current Flow Model for m-Level Diode-Clamped Multilevel Converters
IECON 2006 - 32nd Annual Conference on IEEE Industrial Electronics, 2006Multilevel converters have gained much attention in recent years since they have been a key technology of power electronics to reach the high power ratings required by many applications. Some topological limitations such as dc side voltage balancing, however, have hindered the use of these converters.

A new snubber circuit for diode-clamped four-level inverter and converter
2001 IEEE 32nd Annual Power Electronics Specialists Conference (IEEE Cat. No.01CH37230), 2002This paper proposes a new snubber circuit for a 4-level inverter and converter. The snubber circuit makes use of an Undeland snubber and McMurray efficient snubber as its basic snubber unit, and can be regarded as a generalized combined Undeland and McMurray efficient snubber. The proposed snubber keeps such good features as fewer number of components,

Three-Dimensional Feedforward Space Vector Modulation Applied to Multilevel Diode-Clamped Converters
IEEE Transactions on Industrial Electronics, 2009Simplified space vector modulation (SVM) techniques for multilevel converters are being developed to improve factors such as the computational cost, number of commutations, and voltage distortion. The feedforward SVM presented in this paper takes into account the actual DC capacitor voltage unbalance of the multilevel power converter.
