SVM algorithm of three-level NPC inverter

2008 3rd IEEE Conference on Industrial Electronics and Applications, 2008
On the basis of presenting the principles of space vector modulation (svm) of three-level neutral point clamped (NPC) inverter, an approach to implementation of SVM is proposed. The dwell times of vectors are calculated according to the volt-second balancing. A triangle is adopted to compare with three switching points.

Nine-switch three-level z-source inverter

4th Annual International Power Electronics, Drive Systems and Technologies Conference, 2013
A new configuration of three-level z-source inverter has been proposed. The proposed inverter is based on nine-switch configuration reduces the number of switches compared to other configurations while retaining their attractive capabilities such as voltage boosting and low harmonic content.

Common-mode voltage eliminated three-level inverter using a three-level flying-capacitor inverter and cascaded H-Bridge

2012 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2012
This paper proposes a new 3 level common mode voltage eliminated inverter using an inverter structure formed by cascading a H-Bridge with a three-level flying capacitor inverter. The three phase space vector polygon formed by this configuration and the polygon formed by the common-mode eliminated states have been discussed.

Three-level inverters with direct torque control

Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002
Electrical drives with induction motors (IM) and voltage source inverters (VSI), the control of which uses the principle of direct torque control (DTC), ensure accurate and fast torque control with a simple, in principle, control system. Three-level inverters permit the use of double voltage under the same type of switches and reduce IM current and ...

Cascaded Three-Level Inverters with Synchronized Space-Vector Modulation

Conference Record of the 2006 IEEE Industry Applications Conference Forty-First IAS Annual Meeting, 2006
Novel method of synchronized pulse width modulation (PWM) has been disseminated for control of cascaded neutral-point-clamped inverters feeding open-end winding induction motor drive with single dc voltage source. Control algorithms provide in this case full elimination of the common-mode voltages both in each inverter and in the load.

A new soft switching three level T-type inverter

2016 10th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2016
In this paper, a new soft switching T-type three level inverter is proposed. The proposed new converter provides for main switches to turn on with Zero Voltage Transition (ZVT) and turn off with Zero Voltage Switching (ZVS) without any voltage or current stresses.

Diode Clamped Three Level Inverter Using Sinusoidal PWM

2012 International Conference on Communication Systems and Network Technologies, 2012
An 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.

Analysis of Soft Switching Three Level Inverters

2016
This study represents a review of soft-switching three level (S3L) inverters. Inverters are classified two levels, three levels and multilevel inverters basically. Three level inverters that implicated as I or T types are used more commonly than the others.
