This paper compares modulation schemes for the five-phase inverter. A novel interpretation of five-phase to orthogonal axis transformation is presented with the development of main and auxiliary space vector domains. It is shown that the auxiliary space vector domain produces harmonic distortion in the five phase system. A novel space vector modulation strategy is developed to produce voltage in the main domain while cancelling components in the auxiliary domain, resulting in a sinusoidal system. The novel scheme is practically implemented and the production of sinusoidal excitation is demonstrated. Further a dead-banding scheme is also implemented to reduce switching. © 2004 Heriot-Watt University, UK.
