Multiphase permanent magnet synchronous motor PWM technology

Firstly, This paper studied several PWM technologies of multiphase motor's control system: the Maximum-vector SVPWM, the Multi-dimensional SVPWM and the Carrier-based multiphase PWM. Secondly, the principle and the implement method of these PWM technologies were given, and this paper also analyses the advantages and disadvantages of these technologies. Finally, this paper take the 15-phase permanent magnet synchronous motor control system as an example, built the Matlab/Simulink simulation model and studied the different PWM technology and some conclusions were given.
