Investigation Study of Three-Level Cascaded H-bridge Multilevel Inverter
Abstract: This paper analyzed
three-level Cascaded H-bridge Multilevel Inverter (CHMLI) utilizing two modulation
techniques namely Sinusoidal Pulse Width Modulation (SPWM) and Space Vector
Pulse Width Modulation (SVPWM). The performance and the output of CHMLI in
terms of Total Harmonic Distotion (THD) % and circuits complexity were
compared. The simulations models were constructed using MATLAB/SIMULINK. The
results showed the CHMLI produced the lowest THD contents and utilized fewer components.
Moreover, the SVPWM produced less THD than SPWM.
