A Novel Twenty Seven Level Asymmetrical Multilevel Inverter Using Cross Bridges

Abstract Multilevel inverters which are best known for their efficient performance in medium voltages and high power applications are best served in industrial and other purposes. In this paper, a multilevel inverter of twenty seven level is designed with a combination of cross bridge and a H-bridge which results in a stepped alternating voltage output with desired minimum total harmonic distortion, the output results are examined through MATLAB/ Simulink . Comparisons between various types of carrier waves along with PWM techniques. Keywords: Multilevel inverter, Power Electronics, THD, Asymmetric, Cross bridge, H-bridge
