The utilization of solar energy through photovoltaic systems has become increasingly popular in both residential and commercial buildings. This expanding market for renewable energy has created a high demand for power electronics and modulation techniques. Among these techniques, space vector pulse width modulation (SVPWM) stands out as a vector-based approach to the traditional PWM technique employed in inverters for photovoltaic systems. In this paper the concept of SVPWM will be introduced and simulated in line with a full system description using PSIM. The simulated results reveal a better performance with lower percentage total harmonic distortion (%THD) when compared to PWM. The %THD has been reduced from 3.15% to 0.54% for RL when using SVPWM compared to sinusoidal PWM, and reduced from 3.4% to1.4% when using RLC load.
