摘要
分档功率稳定控制系统通过对市电电压进行AD采样,根据输入电压的变化,采用一种中间相位控制的新方法,控制MOS开关输出相应的脉宽,从而使得灯两端的电压稳定在特定的值,卤素灯在各分档需求中都能以稳定功率输出。
Multi-level power control system samples the input voltage, and controls the MOS switch to output the relevant impulse in accordance with the value of the voltage, which is implemented by adopting a new method called “midphase control”, so that the voltage drop of the lamp can be in steady multi-level values, which turns out to be the steady multi-level brightness of lamp.
