Analysis of Different Levels for Generalized Multilevel Current Source Inverter (MCSI) with Different SPWM Methods

This work presents about the analysis and study of Generalized Multilevel Current Source (MCSI) topology. The work begins by comparing a Total Harmonic Distortion (THD) with various types of Sinusoidal Pulse Width Modulation (SPWM) method for controlling the switch with different levels for generalized multilevel current source inverter (MCSI). The type of SPWM method that will be using on this topology focuses on Level Shifted Pulse Width Modulation Technique (LS-PWM), which is Phase Disposition PWM (PD-PWM), Alternated Phase Opposition Disposition PWM (APOD-PWM), and Phase Opposition Disposition PWM (POD-PWM). Next, is the comparing of total harmonic distortion (THD) with different switching frequency for Generalized Multilevel Current Source Inverter (MCSI) in order to determine the best switching frequency value for the inverter. The simulation of the topology is modelled and simulated using MATLAB Simulink software. The analysis shows the Total Harmonic Distortion (THD) output variation of the different types of SPWM method and switching frequency.
