Abstract
Permanent Magnet Synchronous Machines (PMSMs) are popular due to their high efficiency and favorable dynamic properties. In practice, these machines often have a back-emf waveform which deviates from an theoretically ideal sinusoid or trapezoid. In the past, current waveform shaping techniques were developed for these machines to calculate non-conventional current waveforms to reduce the torque ripple. However, in the light of global warming, energy efficiency has become more important than torque ripple in many applications. Therefore, current waveform shaping techniques can be used to focus on maximum efficiency. In this paper, a technique is presented which maximises the efficiency of both the PMSM and the drive simultaneously. A time domain approach is used instead of the classical frequency domain approach. It allows to include many machine aspects which had to be neglected previously, i.e., armature reaction, reluctance, zero-sequence components and iron losses.
