| Abstract: | Compared with the commonly used sine-wave pulse width modulation(SPWM) method,the Space Vector Pulse Width Modulation(SVPWM) method has higher utilization rate of DC voltage and smaller output waveform distortion.This paper introduces the SVPWM control technology into inverters,and builds a model of three phase inverter based on PSCAD/EMTDC simulation platform and details the implementation of SVPWM modulation method with PSCAD/EMTDC software.Through establishment of a complete control system for simulation and research,it gives the simulation waveforms.The simulation results show the advantages of the SVPWM technique,which is more suitable for high-power applications. |
