摘要：The main focus of the paper is to studythe different modulation techniques used for three phaseVSI supplying single phase loads that require neutralconnection. Two types of topology of three phase inverter,namely three-leg and four-leg inverter are considered.PWM techniques used for both the topologies aredescribed. The three dimensional space vector modulationused for four-leg inverter is discussed in a detailedmanner. Though the four-leg inverters are less commonlyused, it is the only possible solution for providing neutralconnection to supply single phase loads from three phaseinverter. The four-leg VSI presents advantages in a widemanner covering less dc link capacitance, high dc linkvoltage utilization and low distortion at output. Theperformance of various modulation strategies has beenanalyzed and verified using simulation in MATLABenvironment.
