چکیده
This paper proposes a novel modulation scheme to reduce the harmonic content of voltages and currents caused by modular multilevel converters with embedded battery cell when employed for application in energy storage systems grid. The reduction total distortion (THD) is obtained injecting selected harmonics modulating wave phase disposition sinusoidal pulse width modulation. main innovation frequency these injected harmonics, most which are kept considerably higher than carrier frequency. injection has further been improved using closed-loop control optimum output. simulations performed tested on MATLAB-SIMULINK demonstrate satisfactory both voltage current THD without any counter effect.

Harmonic Elimination in Multilevel Converters
A method is presented to compute the switching angles in a multilevel converter so as to produce the required fundamental voltage while at the same time not generate higher order harmonics. Using a fundamental switching scheme, previous work has shown that this is possible only for specific ranges of the modulation index. Here it is shown for a three DC source multilevel inverter that, by modif...

متن کاملHarmonic Reduction Using Multilevel Inverter Concepts
Solar energy sources are widely available, but in the form of DC source. It is connected in distribution system by means of converting DC/AC supply. It is achieved by means of inverter. To get efficient AC source we use multilevel inverter (MLI). The popularly used inverter is cascaded H-bridge MLI. As the step increases, the AC output nearly becomes same as sinusoidal. The purpose of the proje...
متن کاملUtilization of CHB Multilevel Inverter for Harmonic Reduction in Fuzzy Logic Controlled Multiphase LIM Drives
Background and Objectives: Despite superior privileges that multiphase motors offer in comparison with their three-phase counterparts, in the field of multiphase linear induction motors (LIMs) few studies have been reported until now. To combine the advantages of both multiphase motors and linear induction motors, this paper concentrates on multiphase LIM drives considering the end effects. Met...
