PERFORMANCE ANALYSIS OF THREE-PHASE CASCADED HBRIDGE MULTI LEVEL INVERTERS

Power generation from renewable energy sources is environment friendly. These are being integrated into the grid to enhance green power generation. It is necessary to enhance system performance by attaining improved output power quality, decreased losses, and fewer filtering components and transformers in order to effectively utilize these resources. There are many energy sources in nature that can be turned into either ac or dc power. The user should be receiving high quality electricity from this converter. Due to their superior harmonic profile and higher power ratings, multilevel inverters are becoming more and more used in highpower applications. Inverters with many levels take precedence over those with just two levels. In this study, a cascaded Hbridge multilevel inverter with a single hardware topology, based on sinusoidal pulse width modulation-phase disposition (SPWM-PD) modulation techniques, has been assessed. This study uses FFT techniques to demonstrate the total harmonic distortion (THD) performance of the suggested inverter.
