本文研究了交流调速电动机驱动器的一些应用问题。高PWM频率或高dv/dt对电机端电压和轴承电流的影响已得到解决和解释。缓解技术已被证明可以显著降低电机端子处以及电机绕组内的瞬态峰值电压和dv/dt。这种减少有助于提高PWM电机驱动系统的可靠性。
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.
