Multilevel converters are effective means of reducing harmonic distortion and dv/dt of the output voltages, which makes this technology applicable to utility interface and drives. In this paper, Multilevel Converter for power conversion is proposed. The voltage balancing at the terminal is achieved through proper selection of switching states. The switching scheme is defined by Space Vector Modulation. A fuzzy controller need to be interfaced with the system using SVM for optimal voltage operation and error minimization .The main feature of the proposed SVM switching strategy is that it enables balancing voltages of the dc capacitors, with no requirement of additional controls or auxiliary devices and higher magnitude of ac-side voltage with reduced harmonic concept in the output waveform. The proposed idea is demonstrated in simulation to evaluate the validity of the concept in MATLAB.
