要旨

Multilevel inverters (MLI’s) have been used widely for high power and medium power DC-AC conversion. Researchers are working to reduce total effective cost and enhance the working efficiency of the multilevel inverter. This paper presents a new multilevel hybrid inverter which utilizes eight active powers electronics switches along with asymmetric DC voltage source configuration to synthesize 9-level waveform and produces lower total harmonic distortion (THD) profile comparisons to present typical topologies. SPWM technique is used as a control signal for power electronics switches. Also this paper presents output voltage waveforms and total harmonic distortion (THD) for single phase multilevel Inverter starting from 5-level to 9-level. Result verified with the Matlab/Simulation, shows that as the number of levels increases, the % THD will be reduced.   Keywords: Multilevel inverters, MLI, hybrid topologies, asymmetric and symmetric voltage source configuration, CHB, THD, phase shift pulse width modulation, PWM, sinusoidal pulse width modulation, phase opposition dispositionCite this ArticleYasmeen Fatima, Rameshwar Singh.
