Comparative Analysis of SVM Techniques for a Five-Phase VSI Based on SiC Devices
Multiphase systems provides benefits compared to three-phase systems, such as improved torque per ampere, high power density, better fault tolerance, lower current per phase (due to power-splitting among a higher number of phases), and lower torque ...

This paper proposes a modelling method based on multi‐software co‐simulation to precisely model radiated interference in permanent magnet servo drive systems. The accuracy of the simulation model is validated through comparison with actual measurement results. ABSTRACT High‐frequency switching operations of power switching tubes generate high‐frequency

Space vector pulse-width modulation technique for an eleven-phase voltage source inverter with sinusoidal output voltage generation [PDF]
This paper discusses the space vector pulse width modulation (SVPWM) scheme for an eleven-phase two-level voltage source inverter (VSI), aimed at producing a sinusoidal output voltage waveform. Generalised space vector theory is used to realise the SVPWM.

Power Converter's IGBT Multi‐State Reliability Analysis for Low Failure Rate Operation
This paper proposes a multi‐state reliability analysis for IGBTs in power converters, moving beyond the conventional two‐stage model with a constant failure rate and introduces a multi‐state Markov chain model for voltage source converters under different modulation scenarios.

This paper proposes an improved offline pulse density modulation strategy for the SWISS rectifier to achieve low input current distortion and high power factor at high switching frequencies. Experimental results at 38.4 kHz reduce THDi from over 30% to ≈10%, while high‐frequency simulations at 172.8 kHz achieve THDi of 3.3% and PF = 0.9954.
