Switching technique for multiphase voltage source inverter

This paper presents switching technique for multiphase inverter. The development of two-level five-phase voltage source inverter (VSI) has been thoroughly reviewed and results of this investigation are presented. The combination of large and medium vectors has been examined theoretically while simulations were conducted for verification. The analysis of a five-phase space vector modulation was verified using the Matlab simulation. The simulations were carried out to identify the effectiveness of the combination of large and medium vectors. It was found that the combination of large and medium vectors has significantly reduced the harmonic distortion and therefore, can effectively eliminate the third harmonics which consequently produce a balanced sinusoidal signal.
