—This paper is concerned with the adverse effect of subharmonics generated by a pulsewidth-modulation-controlled voltage source converter supplying an ultrahigh-speed induction machine (USIM) and also with the calculation, simulation, and test of the subharmonic generation. It is mostly believed, except for a few publications, that the impact of(More)
The impact of PWM technique on the operation of ultrahigh speed induction machines (USIM) applied to generate electric power by utilizing renewable energy resources has been studied. The analysis was focused on the subharmonics of PWM wave generating high losses in USIM. The novel contribution is the description of a new special approach for the(More)
