摘要
本文从SRD转矩产生的基本原理出发,在满足其低速运行的斩波限流和转速调节的条件下,推出单脉冲调角方式、双脉冲调角方式、脉宽调制方式和调幅方式四种低速运行的控制方式,给出控制电路框图。并阐明了各种控制方式的性能特点和适用范围。
From the basic principle of torque generation of SRD, this paper presents four kinds of controliing modes of low speed operation——single trigger pulse adjusting mode, dou- ble trigger pulses adjusting mode, pulse width modulation and adjusting amplitude, all of them satisfy both current limitation by means of chopping and speed regulation under the low speed operation conditions, then gives the outline of controlling circuits concerned. The characteristic and the suitble applied fields of them have been described.
