Abstract (AI)
Abstract:This paper presents the selective harmonic elimination technique implementation for hybrid seven-level cascaded multilevel converter. The converter configuration is the cascaded connection of a three-level Active neutral-point-clamped (ANPC) converter and an H-bridge per phase, thus forming a hybrid seven-level multilevel converter. The converter is operated by maintaining the switching frequency of a converter to a minimum value using selective harmonic elimination pulse width modulation (SHE-PWM). Analysis of the topology operated under SHE-PWM is presented on the basis of simulation results obtained from MATLAB/SIMULINK. Index Terms—Multilevel converter, hybrid converter, Active neutral-point-clamped (ANPC) converter, hybrid converter, selective harmonic elimination pulse width modulation (SHE-PWM).
