Performance of a Diode-Clamped Linear Amplifier
IEEE Transactions on Power Electronics, 2008This paper proposes a new high-efficiency diode-clamped linear amplifier, and presents its theoretical and experimental performance. The main circuit of the proposed amplifier consists of series-connected MOSFETs, series-connected dc power supplies and clamping diodes. The circuit configuration is similar to a diode-clamped multi-level inverter, except

Design of Schottky-barrier diode-clamped transistor layouts
1973 IEEE International Solid-State Circuits Conference. Digest of Technical Papers, 1973Describes an approach to the design of Schottky-clamped integrated circuit transistor layouts. Three-dimensional distributed resistances are modeled using a grid of lumped resistors. A computer circuit analysis program is used to obtain a simple lumped equivalent circuit for the clamped transistor.

Capacitor Balance Issues of the Diode-Clamped Multilevel Inverter Operated in a Quasi Two-State Mode
IEEE Transactions on Industrial Electronics, 2008 A new operational mode for diode-clamped multilevel inverters termed quasi two-level operation is proposed. Such operation aims to avoid the imbalance problem of the dc-link capacitors for multilevel inverters with more than three levels and reduces the ...

A Novel Inductor Based Balancing Circuit for Diode Clamped Converters
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018The paper proposes a new balancing circuit for multilevel diode clamped converters (DCC) aimed to keep the DC-Link voltages balanced, regardless of the converter operating condition. The proposed architecture, which is based on the same topology of a DCC leg, is connected to an external inductor and is driven by a specialized modulation technique ...

A new diode-clamp cascade multilevel converter
IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat. No.03CH37468), 2004Cascade and diode-clamp voltage source converter have become increasingly popular in recent years due to their practicability. This paper will present a new diode-clamp cascade multilevel converter that is derived from these two topologies. The new concept of the novel diode-clamp cascade converter is based on the connection of multiple three-level ...

Fundamentals of a new diode clamping multilevel inverter
IEEE Transactions on Power Electronics, 2000The conventional diode clamping inverter suffers from such problems as DC link unbalance, indirect clamping of the inner devices, turn-on snubbing of the inner DC rails as well as series association of the clamping diodes etc. It is due largely to these problems that the application of the conventional diode clamping inverter in practice has been ...

Comparative Harmonic Analysis of Diode Clamped Multi-Level Inverter
2018 3rd International Conference On Internet of Things: Smart Innovation and Usages (IoT-SIU), 2018Power quality has been main issue among the consumers nowadays. The consumer devices are based on power electronics devices for better efficiency which tend to introduce various current harmonics in our power system at the point of common coupling. With the accession of renewable energy sources as the better and environment friendly alternative to meet

Analysis of the three-level diode-clamped split-source inverter
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016This paper studies the integration of the two-level split-source inverter (SSI) concept into the three-level diode-clamped inverter configuration. The proposed three-level diode-clamped-based SSI (3L-DC-SSI) uses two isolated dc sources, two inductors, two capacitors, and six input diodes with the three-level diode-clamped bridge.
