Improve the Stability of the Segmented Traction Drive by Reducing the Harmonics with Controller

Abstract

This paper represents, reduced harmonics in the three phase three module inverter. If the module number increases the Total-harmonics-distraction (THD) value of the traction drive reduced. And the THD value is tremendously reduced by using controller with three phase three module inverter. Here Proportional Integral (PI) is used as a controller. The THD values for the three modules with controller and simulink results are placed below. The performance a characteristic of the traction drive is improved compared with and without controller. And the simulink results are placed below.
