Speed squirrel cage motor control is an area of research that has been in evidence for some time now. In this paper, a nonlinear controller presented the drives, based on combination between input-output feedback linearization (IOLC) technique and sliding mode (SMC) to create new which (SIOLC) motors associates by NPC five levels inverter PWM technical used variation its speed, where it control...

Abstract A general growth is being seen in the use of renewable energy resources, and photovoltaic cells are becoming increasingly popular for converting green solar into electricity. Since voltage produced by DC, an inverter required to connect them grid with or without transformers. Transformerless inverters often used their low cost power loss, light weight. However, these suffer from leakag...

This article introduces a single-phase five-level multilevel inverter based on six switches and two transformers. The proposed converter requires single dc input source with low voltage. disposition of makes it possible to build the transistors six-pack module off-the-shelves, traditionally used three-phase inverters, which simplifies manufacturing process. increases voltage transformers; for t...

This article presents a novel dual-mode five-level common grounded type (5L-DM-CGT) transformerless inverter topology for medium-power application with wide input voltage range (200–400 V). It consists of nine semiconductor switches, two inner flying-capacitors, and small LC filter at the output side. Due to direct connection negative terminal photovoltaic neutral point grid, there is no leakag...

In this paper a new 5-level single phase symmetrical cascade multi-level inverter is proposed. The proposed topology contains combination of unidirectional and bidirectional power switches based on output voltage level number. The number of power switches and withstanding voltage of powers witches were reduced related to the other topologies. This configuration can be extended to the n-level in...

Multilevel converters have received serious attention on account of their capability high voltage operation, efficiency, and low electromagnetic interference. It has many advantages compared to conventional two-level inverters such as dc-link voltages, reduced harmonic distortion, fewer stresses, interferences. The multilevel been used for STATCOM widely it can improve the power rating compensa...
