ABSTRACT

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 dc-link capacitance without introducing any significant voltage ripple at the dc-link nodes. The proposed operation can be generalized for any number of levels. The validity of the proposed multilevel inverter operational mode is confirmed by ....etc

Single-Phase Seven-Level Grid-Connected Inverter
for Photovoltaic System



I. INTRODUCTION
THE ever-increasing energy consumption, fossil fuels
soaring costs and exhaustible nature, and worsening
global environment have created a booming interest in renewable
energy generation systems, one of which is photovoltaic.
Such a system generates electricity by converting the Sun s energy
directly into electricity. Photovoltaic-generated energy can
be delivered to power system n ....etc

Diode Clamped Multilevel Inverter Fed Induction Motor


INTRODUCTION

Two level voltage source inverters produce an output voltage or a current with levels either 0 or Vdc

In high power and high voltage application these two level inverters, however, have some limitations in operating at high frequency mainly due to switching losses and constraints of device ratings.

Unique structure of ML-VSIs allow them to reach high voltages with low-harmonics without use of transformers ....etc

Abstract:
This paper deals with the direct torque control of capacitor multilevel VSI actuators. The active control strategy high voltage I high power induction motors fed by floating egy for well-balancing the capacitor voltages is presented highlighting an optimal pattern. The efficiency of this approach is compared to the well-known passive method and it is illustrated by simulation. In the next section, a controlled cycle based algorithm is proposed as an attractive solution for a high performance torque control ....etc

seven level inverter ppt

This paper proposes a new solar power generation system, which is composed of a dc/dc power converter and a new seven-level inverter. The dc/dc power converter integrates a dc-dc boost converter and a transformer to convert the output voltage of the solar cell array into two independent voltage sources with multiple relationships. This new seven-level inverter is configured using a capacitor selection circuit and a full-bridge power converter, connected in cascade. The capacitor selection circuit converts the two outpu ....etc
