Abstract :
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 inverter, built a model of three phase inverter based on PSCAD/EMTDC simulation platform and detailed the implementation of SVPWM modulation method with PSCAD/EMTDC software. Through the establishment of a complete control system to simulate and research, giving the simulation waveforms. The results showed the advantages of SVPWM technique are more suitable for high-power applications.
