  • Abstract
    Ultra-high speed electric machines (speed is in the order of 100 krpm) supplied by PWM inverters are extremely vulnerable to subharmonics. The main source of subharmonics is in the low frequency modulation ratio of the PWM inverters available. The paper presents methods for the calculation of subharmonics.
