A Novel Cascaded Multilevel Inverter with Half Bridge and Full Bridge Cells in Series
نویسنده
چکیده
In this paper, a modular three-phase multilevel inverter specially suited for electrical drive applications is proposed. Unlike the cascaded H-bridge inverter, this topology is based on power cells connected in cascade using two inverter legs in series. A detailed analysis of the structure and the development of design equations for the load voltage with n levels are carried out using pulsewidth-modulation phaseshifted multicarrier modulation. Finally a novel Cascaded multilevel inverter with half bridge and full bridge cells in series are proposed. A Matlab/Simulink based model is developed and simulation results are presented. KeywordsCascade systems, inverters, multilevel systems, pulsewidth modulation (PWM).
