Abstract :
Three space vector modulation schemes are analyzed for a four-leg voltage source inverter. The analysis is performed with respect to switching losses and total harmonic distortion under both balanced and unbalanced load conditions over the entire range of modulation index values and over varying load power factor angle. The analysis has been verified using simulation
