This Paper aims to extend the knowledge about the performance of different cascaded multilevel inverter through harmonic analysis. Large electric drives and utility require advanced power electronics converter to meet high power demands. As a result, multilevel power converter structure has been introduced as an alternative in high power and medium voltage situations. A multilevel converter not...

This paper presents detailed modeling and simulation of a compensator for Load balancing and harmonics Compensation based on a five-level cascaded H-bridge multilevel voltage source inverter. This type of compensator, which is installed in parallel with the load, is usually referred to as the shunt active power filters (APF). Nowadays use of high voltage non-linear loads are widely used in indu...

Economic benefits from using power electronics equipment are much more visible than losses caused by harmonics produced by this equipment. Consequently, we enter the New Millenium with sources of harmonic distortion more and more distributed over distribution systems. We have to confess that we are much more effective in generating harmonics than in their elimination. This situation should not ...

Thyristor controlled static compensators consist of two basic schemes, TCR and TSC. Owing to the discontinuous current in TCR, current harmonics are generated in the supply system. This paper introduces two methods for the reduction of these harmonics. On the basis of the coordination or uncoordination of turn ratios with harmonic reduction levels, each method is described in two alternative sc...

This paper presents a unified approach for generating pulsewidth-modulated patterns for three-phase current-source rectifiers and inverters (CSR/Is) that provides unconstrained selective harmonic elimination and fundamental current control. The approach uses the chopping angles or gating patterns developed for voltage-source rectifiers and inverters in combination with a logic circuit to genera...
