A Comparative Analysis Between PI And PID Controllers For Different Levels Of Diode Clamp Multilevel Inverter To Improve Inverter Performance

This work presents about a comparative analysis between PI and PID controllers for different levels of Diode Clamp multilevel inverter to improve inverter performance. The Multilevel Inverter function as power electronic devices that generated the Alternating Current by reshaping the Direct Current and provided the output as desired. Diode Clamped is one of the three topologies of Multilevel Inverter and are used in industry nowadays. The harmonics are components that can cause the quality of the power deteriorated. This paper focus on analyzing the harmonic component of the voltage output for 5, 7 and 9 level topologies of Diode Clamped. This technical paper also present about the different of using PI and PID controller using APOD-SPWM technique in controlling the Diode Clamped in terms of Total Harmonic Distortion(THD). This analysis are obtained by simulating all circuit of Diode Clamped in software MATLAB/SIMULINK.
