  • Abstract
    In this article, some application issues for adjustable speed AC motor drives have been investigated. The effects of high PWM frequency, or high dv/dt on the motor terminal voltages and bearing currents have been addressed and explained. Mitigation techniques have been shown to significantly reduce the transient peak voltage and dv/dt at the motor terminals, as well as within the motor windings. This reduction contributes to improved reliability of PWM motor drive systems
