可控硅调压器 三相 纯阻性负载 电力电子技术基础例程(biSCR 3phase)

超简单断电复原3档亮度调光程序,每次开机都是低亮，不晃眼 低亮不是使用Pwm，而是使用电阻漏一部分电流给LED，超省电，无频闪，亮度随便调 源程序是东成的(3 super simple file recovery power brightness dimming process, each boot are low-light, non-dazzling light rather than the use of low-Pwm, but part of the use of resistance leakage current to the LED, ultra-low power, no strobe, just tune brightness source procedures of the East into)
