| Abstract: | With different target waveforms of the midpoint of the bridge legs,threephase voltage source inverter(VSI) has various types of modulation algorithms,such as square-wave modulation,trapezoidal-wave modulation,SPWM modulation and SVPWM modulation.From the point of view for study,the paper presents the operation principle analysis of three-phase voltage source inverter when square-wave modulation with 120°conduction,150°conduction and 180°conduction by means of simulation,respectively. Then a brief comparative analysis is also provided. |
