A computational tool for simulation an design of multilevel inverters

Abstract

This paper proposes an aiding tool to the design and development of multilevel inverters studies using the cascade configuration to achieve output voltage waveform shaped step with several levels. The program contribution is to aid inverter simulation using the software Pspice Orcad besides set the best switching instant of each level which work in harmonics selective elimination, contributing to a lower THD of the output voltage waveform. This software also shows a flexible code which can be automatically adapted for implementation in a microcontroller or DSP.
