Diode Clamped Three Level Inverter Using Sinusoidal PWM
2012 International Conference on Communication Systems and Network Technologies, 2012An inverter is a circuit which converts dc power into ac power at desired output voltage and frequency. The a.c. output voltage can be fixed at a fixed or variable frequency. This conversion can be achieved by controlled turn ON & turn OFF or by forced commutated thyristors depending on applications.

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 ...

Modeling of diode clamped inverter using SPWM technique
2017 International Conference on Green Energy Conversion Systems (GECS), 2017Certainly many applications in industrial field have begun to require nowadays high power. However some industrial appliances require for their operation medium or low power. So using a high power source for all types of loads may be a benefic solution to some motors, while it makes damage for other loads.

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 Reduced Switch Diode Clamped Multilevel Inverter Topology
2020 IEEE International Conference on Computing, Power and Communication Technologies (GUCON), 2020In this work, a new diode clamped multilevel inverter topology with reduced switches and component counts is proposed. This topology can generate desired level of output voltages with lower number of switches and clamping diodes. A scaled version of the proposed topology is discussed with relevant figures of merits. Two different levels of inverters (5

Low-power dynamic termination scheme using NMOS diode clamping
IEEE Journal of Solid-State Circuits, 1999An NMOS diode clamped termination (NDCT) with NMOS threshold voltage (V/sub th/) of around 0 V is proposed as a dynamic termination for a high-speed/low-power chip-to chip interconnection scheme. Both simulation and experimental results for several benchmark circuits show that, compared with open termination, the magnitudes of both overshoot and ...

Hybrid SVPWM strategy for diode-clamped 3H-bridge inverter
2014 17th International Conference on Electrical Machines and Systems (ICEMS), 2014The paper presents a novel space vector modulation strategy for a single phase three-level neutral-point-clamped(NPC) inverter. Based on the operating principle of NPC inverter, this strategy overcomes one of the main problems of this inverter, which is the DC-link capacitors voltage unbalancing problem that appears in the neutral point under some ...

Simulink Implementation of PWM Strategies for Diode Clamped MLI
International Journal of Engineering Trends and Technology, 2014Multilevel inverters has got more concern over conventional two level inverters because of their features like yielding output with low harmonics, output tending to sinusoidal, the voltage stress across each switching device is low. The diode clamped inverter is widely multilevel inverter configuration due to ease of operation when compared to other ...

A matrix converter without diode clamped over-voltage protection
Proceedings IPEMC 2000. Third International Power Electronics and Motion Control Conference (IEEE Cat. No.00EX435), 2002In this paper, the design and testing of a new protection strategy for a matrix power converter feeding an induction motor is described. The new protection strategy, with excellent overvoltage protection, allows to remove the large and expensive diode clamp.
