Abstract

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 determination of subharmonics, the presentation of its results and their comparison to the theory known from literature and to the results obtained by computer simulations and laboratory tests. Both qualitative and quantitative serious discrepancies between the results of the new special approach verified by simulation and tests on the one hand and the familiar theoretical results are accentuated.
