PWM控制回路的设计
A Design for PWM Dominating Return Circuit
【摘要】 围绕三相异步电动机的变频调速,运用电子技术,构造了一种PWM控制模式,并以此为依据实现了高频率、大范围和精密控制的无级调速.
【Abstract】 This article centers on 3-phase AC motor′s adjusting speed by changing frequency. It uses electric technology to constitute a kind of PWM′s operation framework to achieve the goal of non-step adjusting speed in high frequency, large scope and accurate control.
