Multicarrier PWM strategies for multilevel inverters

IEEE Transactions on Industrial Electronics, 2002
Analytical solutions of pulsewidth-modulation (PWM) strategies for multilevel inverters are used to identify that alternative phase opposition disposition PWM for diode-clamped inverters produces the same harmonic performance as phase-shifted carrier PWM for cascaded inverters, and hybrid PWM for hybrid inverters, when the carrier frequencies are set ...

Multilevel Inverter Based Distribution STATCOM: Application of the Cross-Switched Multilevel Inverter

Electrical Engineering (ICEE), Iranian Conference on, 2018
Multilevel inverters are widely used in various applications due to their interesting features. They can be connected to the grid as a STATCOM to improve grid power quality and voltage control. In this paper, a distributed STATCOM (DSTATCOM) is provided based on cross-switched multilevel inverter which is connected to a low voltage distribution system.

Control of novel multilevel inverter

2015 IEEE Students Conference on Engineering and Systems (SCES), 2015
The focus of this paper is to develop and implement the new topology of multilevel inverter and study its performance The developed new MLI topology uses less number of switches and hence it is simple in control, cost effective and efficient. The proposed model is designed for 11-level and a prototype laboratory model is implemented.

Multilevel inverter as var-compensator

2013 IEEE XXXIII International Scientific Conference Electronics and Nanotechnology (ELNANO), 2013
Multilevel inverter consists of base cells that have the same structure as active power line conditioner. This allows to use the inverter cells as the VAR-compensator in uninterruptible power supply systems. The advantage of this system is increasing the allowable current range that can be correctly compensated.

Overdistention operation of cascaded multilevel inverters

IEEE Transactions on Industry Applications, 2003
Established research has shown that cascaded multilevel inverters can provide more voltage vectors per number of active semiconductors compared to typical multilevel converters. This feature is significant for increasing the drive performance as well as reducing the drive complexity and losses.

A new topology for multilevel inverter

2015 IEEE 10th Conference on Industrial Electronics and Applications (ICIEA), 2015
Single-Phase multilevel converters are suitable for medium power applications as photovoltaic systems and switched reluctance machines, whereas, three-phase inverters are widely used in industries for high power applications. A new single phase topology and its three-phase applications with reduced device count is proposed so that the complexity as ...

Flux modulation for multilevel inverters

IEEE Transactions on Industry Applications, 2002
This paper presents a new flux modulation approach for the closed-loop control of the output voltage of multilevel inverters, using hysteresis with a rectangular bounding box in the synchronous d-q reference frame and a simple set of switching rules. The modulator is constrained to select only from the three active space vectors nearest to the target ...

Analysis of Cascaded multilevel inverter

India International Conference on Power Electronics 2010 (IICPE2010), 2011
There is a new control strategy to control Cascaded multilevel converters in a multi-string configuration for single phase grid connected systems. This topology generates high quality output current under any circumstances specifically in partial shading, while tracking the MPP of each string independently. The topology does not consist of any extra DC-
