In conclusion, the study shows that the sine PWM method is the most effective modulation method for the single-phase inverter with a 10 kHz carrier frequency and 50 Hz fundamental frequency. Its low THD, high efficiency, and robust output waveform make it the ideal choice for a variety of applications such as solar power systems, and motor drives.
CONCLUSION The experimental results show that the amplitude modulation index (ma) and the frequency ratio (mf) formed from the reference signal and carrier signal affects the harmonic content of the generated inverter SPWM.
A comparative analysis is conducted with the conventional multilevel inverter (MLI) topologies, specifically the cascaded H-bridge (CHB) and H5 inverter configurations. The investigation delves into the impact of modulation index variations, load fluctuations, and modulation methods on the inverter''s operational performance.
If the reference signal VR, performs at a frequency fR, amplitude AR, and the carrier signal VCr performs at a frequency fCr, amplitude ACr, then the ratio of amplitude modulation (ma), which is also called the modulation index can be determined as follows : where, A0 is amplitudo of fundamental output AC voltage, Vi is input DC voltage.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
