A Complete Analysis of New Generalized Asymmetric Multilevel Inverter Topology

ABSTRACT This paper presents a new generalized topology of the asymmetric multilevel inverter. Each unit generates 9 levels with two dc sources and eight power switches. There is no need of additional circuit to generate negative voltage levels. A generalized topology can be developed by a series connection of n number of units which can generate higher voltages with low harmonics. Multi-carrier sinusoidal pulse width modulation (MC-SPWM) scheme is used to attain quality output voltage. Simulation results using MATLAB and experimental results are presented to verify the performance of proposed topology. Keywords: Asymmetric, multilevel inverter (MLI), MC- SPWM power switches, total harmonic distortion (THD).
