Application and Simulation of SVPWM in three phase inverter
Comparing with commonly used sine-wave pulse-width modulation(SPWM) method, Space Vector Pulse Width Modulation (SVPWM) method has higher utilization rate of DC voltage and smaller output waveform distortion. This article introduced SVPWM control technology into three-phase grid-connected inverter, created a main circuit mathematical model of three-phase grid-connected inverter and detailed the implementation of SVPWM modulation method with Matlab software. Through the establishment of a complete closed-loop system to simulate and research, giving the simulation waveforms and output grid-connected current waveform. The simulation results showed the advantages of SVPWM technique are more suitable for high-power applications.
