摘要
In this paper, a new optimal space-vector pulse-width modulation (SVPWM) technique is presented for three-phase voltage source inverters. 6 sectors are redivided into 12 ones based on SVPWM, and combining with local over-modulation method, the discontinuous SVPWM strategies called as DSVPWMx including DSVPWMP, DSVPWMN, DSVPWMPN1 and DSVPWMPN3 are proposed. The principle of the new DSVPWMx is developed, and essential relations among the different DSVPWMx strategies are discussed. The simulation and experimental results verify that the DSVPWMx strategies are right and feasible.
