Modeling of diode clamped inverter using SPWM technique

2017 International Conference on Green Energy Conversion Systems (GECS), 2017
Certainly 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, 2018
The 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), 2020
In 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, 1999
An 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), 2014
The 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 ...

Integrated Schottky-diode clamp for transistor storage time control

Proceedings of the IEEE, 1968
Integration of a Schottky-diode antisaturation clamp with an n-p-n silicon transistor is described. The technique is compatible with beam-lead integrated circuit technology and offers an alternative to gold doping for storage time control.

Simulink Implementation of PWM Strategies for Diode Clamped MLI

International Journal of Engineering Trends and Technology, 2014
Multilevel 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), 2002
In 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.

Voltage Balancing in Five-Level Diode-Clamped Power Converters

IFAC Proceedings Volumes, 2013
Abstract This paper addresses the voltage imbalance problem of the dc-link capacitors in multilevel power converters. Considering the five-level diode-clamped converter, a mathematical analysis of the capacitor voltage difference dynamics is carried out.

Current sharing between diode clamps of polar capacitor bank

IEEE Transactions on Industry Applications, 2002
The layout of a capacitor bank with clamping diodes is investigated based on an experimental 5.5-kJ energy storage unit for pulsed power applications. While the current sharing between parallel-connected capacitors is good, it is not the case with parallel-connected clamping diodes.
