Advantages of operating a Permanent Magnet Synchronous Machine (PMSM) without a position sensor are many and are well known. This paper presents a study of the effects of space harmonics in the incremental inductances and their impact on the machine saliency. The effects of space harmonics exclusively due to the machine (i.e., the saturation saliency distribution) are given particular consideration...
A new NPC three-phase inverter with three-phase coupled inductor is presented in this paper. Initially the power stage diagram is shown and discussed. Their main characteristics are described and the more relevant waveforms, generated by simulation, are shown. Next, the employed modulation and converter operation are discussed and some relevant figures are presented. After that, the presence of the...
