Simulation Modeling for Comparative Analysis of SPWM and SVPWM in Solar PV Inverters

The performance of space vector pulse width modulation (SVPWM) and sinusoidal pulse width modulation (SPWM) techniques for solar photovoltaic (PV) inverters is compared in this study with an emphasis on power consumption, harmonic distortion, and efficiency. Using simulation and hardware implementation, the investigation shows that SVPWM performs better than SPWM. Improved DC bus voltage utilization, decreased overall harmonic distortion, and enhanced inverter efficiency with SVPWM are some of the main conclusions. Software simulations were used in the study, and their validity was confirmed by hardware implementation. A 125 kW rooftop solar PV system at Walchand College of Engineering, Sangli, was used to test and confirm the hardware results. SVPWM is recommended for highperformance solar PV systems because it can lower switching losses and increase system efficiency, while SPWM is still practical for low-power, cost-sensitive applications. The study comes to the conclusion that SVPWM-based control schemes can greatly improve the performance of solar PV inverters, especially in residential and commercial PV installations. This emphasizes how crucial advanced PWM techniques are to the optimization of renewable energy systems.
