双向可控硅控制角与输出电压关系

1、.众所周知，使用双向可控硅的通与断可以实现交流电输出电压的调节。输出电压的控制采用控制可控管的导通角来实现。控制角是指可控硅断开的正弦波角度。输出电压与输入电压、及控制角的关系表：正弦波半周（90度角)面积 2 交流电输入电压(V) 230 1角度对应的弧度 0.0174 弧度与角度对应关系： 2 = 360度控制角角度 控制角弧度 Sin(x)积分 积分百分率 输出电压0 0.0000 0.0000 0.00% 230.001 0.0174 0.0002 0.01% 229.982 0.0349 0.0006 0.03% 229.933 0.0523 0.0014 0.07% 229.844
