New Topology Of Asymmetrical Nine-Level Cascaded Hybrid Bridge Multilevel Inverter

recently the researchers in multilevel inverter (MLI) have interested in reducing the number of switches and sources with acceptable total harmonic distortion (THD %) of the output voltage waveform to reduce losses and costs. This paper present a new concept of asymmetrical cascaded hybrid bridge multilevel inverter (ACHB-MLI) to produce nine-level output waveform with only seven switches and two DC supplies instead of sixteen switches and four DC supplies used in the conventional cascaded hybrid bridge multilevel inverter (CHB-MLI). The proposed topology is investigated under phase disposition pulse width modulation technique (PD-PWM) and the results have been compared with conventional cascaded multilevel inverter. The simulation results are provided using MATLAB Simulink.
