Power Quality Analysis of AC-DC Controlled Rectifiers Fed DC Separately Exited Motor Drive

The power quality analysis of a single phase different AC-DC controlled converter fed separately excited DC motor drive at different load and firing angle operating conditions is presented in this article using the MATLAB/Simulink software platform. In addition, the proportional integral (PI) controller is used to control the speed of the DC motor drive. The Ziegler Nicholas tuning method is used to obtain the PI controller parameters. This work considers single phase semi, full, and dual converters for this power quality analysis study. The output voltage, rms output voltage, distortion factor, displacement factor, power factor, output voltage/current ripple, and torque ripple are used to evaluate the performance of various converter fed DC drives with PI controllers. Finally, in power quality analysis, understand the impact of the controller and design for it.
