摘要
介绍了基于TMS320F240的DSP芯片可控硅脉冲数字触发控制方案,重点是关于移相触发角α的反余弦拟合运算,延时脉冲调制输出,完成数字余弦移相单元的功能及在现场的应用情况;根据不同的用途,适当更改控制触发脉冲软件,可使本方案适用于不同方式的可控硅控制的调节器。
The thyristor pulse digital triggering mode based on DSP chip TMS320F240 is described.The focuses are on the anti-cosine fitting operation of the triggering angle α and the delayed pulse modulated output to perform the function of digital cosine phase-shift unit.This controlling mode is adequate for the thyristor-controlled regulators in any forms by changing the triggering pulse software appropriately according to different uses.
