Enhanced Space Vector Based Pulse Width Modulation (SVPWM) for Cascaded H-bridge Multilevel Inverter (CHBMI)

Le résumé fourni par la source

The Space Vector Modulation (SVM) technique is extensively employed in multi-stage converters which has several benefits like higher DC bus use in conjunction with sine PWM and reduced harmonics, resulting in larger area vectors than the conventional -degree inverter. As a result, we can improve multilevel converter satisfaction. However, as the number of necessary converter stages increases, so will the complexity and calculation requirements for the optimum switching sequence. As a result, we encounter several issues when putting simulations and experiments into practice. It is suggested to use a popular SVM approach that creates any stage with a cascaded H-bridge (CHB) structure that make SVM techniques simpler and decrease calculating number. They also produce advantageous circumstances for using this shape in industries more widely. The concept is extended for nine-stage CHBMLI, and the related THD was compared to seven- and nine-level CHBMLI. In MATLAB/Simulink, simulation paints of the suggested topology could be run.
