Power Quality Performance evaluation of Cross Switched CT type multilevel inverter by Implementation of Phase Disposition Multicarrier Pulse Width Modulation Scheme

Abstract

A multilevel inverter is being used in modern power systems to make electricity reliable and stable. On the other hand, traditional multilevel inverters are having disadvantages as well. This paper evaluates CT type cross switch multilevel inverters using eight switches. Implementation of cross switch is by connecting CT type back to back with the help of cross switches. This configuration can be used for both asymmetric and symmetric. The performance is evaluated by Phase disposition (PD) technique. This configuration has reduced THD while having high efficiency in comparison to other techniques. Execution of the model is on MATLAB/Simulink.
