A new multilevel DC-AC converter topology with a reduced number of switches controlled by the multi-carrier sinusoidal PWM technique

In this paper, a new multilevel inverter topology is proposed with a reduced number of switches and no passive components. The proposed inverter generates a 7-level output voltage, capable of supporting high powers with minimum total harmonic distortion (THD) and involves a reduced number of switche...

Summary:In this paper, a new multilevel inverter topology is proposed with a reduced number of switches and no passive components. The proposed inverter generates a 7-level output voltage, capable of supporting high powers with minimum total harmonic distortion (THD) and involves a reduced number of switches. This paper elucidates the operating modes, voltage stress vices and number of voltage sources compared to conventional inverter topologies of the same number of levels. To improve the performance of our inverter the multicarrier sinusoidal PWM control (MSPWM) is used. The simulation results of the proposed inverter topology are checked using matlab/simulink have been analyzed with different types of control and modulation indices.
