摘要
采用相量图的方法,对软启动器的主电路接R负载时的工作过程分别进行了定量分析,求出了负载在各种控制角范围中负载电压和晶闸管端电压的解析式,绘出了理想情况下负载电压的波形,建立了控制角变化的整个范围内输出电压有效值与控制角的数量关系。
The paper gives the quantitative analysis of the main circuit of soft-starter using phase diagram while it connected with resistive load, and provides the range of controlling angle of the loads,at the same time, the analytic expressions of output voltage and the voltage of thyritors are derived, then the output voltage waveform of ideal condition is drawn out by mean of MATLAB, and the numerical relation between the effective value of output voltage and the controlling angles within the range of the controlling angles is given.
