The subject of the research is control algorithms for aseven-phase converter that implement space-vector voltage modulation motor as an alternative to a three-phase engine in modernelectric traction. study used elements set theory, combinatorics,Fourier series expansion and vector analysis. Checking results wasimplemented on special stand experimental studies spatial vectorvoltage seven-phase m...

With the rapid development of wide-band gap semiconductor chip and package technologies, voltage class commercial silicon carbide (SiC) device is gradually improved. This paper concentrates on latest 3.3-kV full SiC-based metal oxide field-effect transistor (MOSFET) its application in railway traction. First, compared with Si-based insulated-gate bipolar (IGBT), MOSFET shows lower switching los...

In this study, we compared the effects of Type I benzodiazepine receptor-selective agonists (zolpidem, quazepam) and Type I/II non-selective agonists (zopiclone, triazolam, nitrazepam) with either an ultra-short action (zolpidem, zopiclone, triazolam) or long action (quazepam, nitrazepam) on motor coordination (rota-rod test) and muscle relaxation (traction test) following the recovery from thi...

I have tested two contending views of chromosome-to-pole movement in anaphase. Chromosomes might be pulled poleward by a traction fiber consisting of the kinetochore microtubules and associated motors, or they might propel themselves by a motor in the kinetochore. I cut through the spindle of demembranated grasshopper spermatocytes between the chromosomes and one pole and swept the polar region...

This report explores detecting inter-turn short circuit (ITSC) faults in surface permanent magnet synchronous machines (SPMSM). ITSC faults are caused by electrical insulation failures in the stator windings and can lead to shorts to ground and even fires. This report proposes methods for detecting these faults using a moving horizon observer (MHO) to reduce the chance of electrical shocks and ...
