In this paper, three overmodulation techniques for the three-to-five-phase indirect matrix converter (IMC) are proposed. The first technique utilizes only the adjacent large vectors in the sector in which the reference output voltage vector lies. The second technique improves on that by continuously adapting vector elimination in the $d_2{-}q_2$ vector space based on the output voltage requirements...
Switched inverters generate fast rates of change of common-mode voltage and are an unwanted side-effect in variable speed drive systems operated with PWM inverters. Whilst techniques have been reported that theoretically eliminate the common-more voltage, when the dead-time effects and the practical transient performance of semiconductors are considered, a common-mode voltage is still generated, even...
The application of concentrated windings (CW) in interior permanent magnet (IPM) machines has been claimed to enhance high-speed performance by increasing flux-weakening capabilities of the machine. However this is at the expense of a high cogging torque, decreased winding factor as well as saliency ratio. This paper illustrates the effects of implementing well known methods to improve open circuit...
