Modeling and Comparison of Space Vector PWM schemes for a Five-Phase Induction Motor Drive

Multiphase induction machines are being considered for various applications in transportation and power sector. This is because of their capability to achieve enhanced power when compared to its three-phase counterparts. In addition to this, a multiphase drive improves the reliability at the system level, thus contributing to overall system efficiency. A detailed dynamic modeling of five-phase IM with various space vector pulse width modulation (SVPWM) techniques are presented in this paper. These SVPWM techniques are compared in terms of total harmonic distortion. A modified SVPWM for five-phase drive is also presented. In order to verify the effectiveness space vector modulations, necessary simulation results are provided using MATLAB/SIMULINK software and experimental analysis are performed on a five-phase inverter developed in the laboratory.
