abstract

  • © 2015 IEEE. In this paper space vector model of a fifteen-phase voltage source inverter (VSI) is presented. The space vector Pulse Width Modulation (SVPWM) of a fifteen-phase voltage source inverter (VSI) with the aim of producing sinusoidal output waveform, is illustrated. Generalized space vector theory is used to model the inverter and the SVPWM. As per the general inverter switching theory there are 215 = 32768 switching states are possible that yield 32766 active space voltage vectors and two zero voltage vectors at the origin. Out of the total 32766 active voltage vectors, 210 voltage vectors are utilized for the implementation of SVPWM. The sinusoidal voltage is obtained by controlling the duty cycle the voltage space vectors of d-q plane when voltage space vectors of other six x-y planes are set to zero. Maximum modulation index is used to get balanced sinusoidal output. The theoretical results are verified by simulation and experimental results with R-L load.
