Abstract
Harmonic currents always exist in a five-phase permanent magnet synchronous machine (PMSM) due to some disturbances. This letter proposes a unique modulation scheme to synthesize the control voltage in the harmonic subspace, xy-space, to suppress harmonic currents actively. The advantage of proposed modulation scheme is that it is decoupled from the modulation process in the αβ-space, thereby not affecting the torque output or dq-axis currents. Firstly, according to the αβ-space control voltage reference, the action time ranges of two large and two middle voltage vectors adjacent to the control voltage reference are determined. Secondly, the ranges are divided into several segments equally. Then, the best action time is selected from these segments to generate a proper control voltage in xy-space. Finally, the switching pattern of the inverter is designed with the selected action time. Experiments have been implemented to verify the effectiveness of proposed modulation scheme.
