Development of current control for three phase multilevel inverter

Inverter is a device, a type of electronic converter in which purpose is to convert a DC signal to AC signal. This project aims to develop a current control method for a multilevel inverter. The purpose of adding a controller is so that the output from the said device, can be controlled and maintain...
