什么是 PWM

“ PWM（脉冲宽度调制）”是电子组件领域中使用的数字信号处理方法之一。

PWM是使用数字信号模仿模拟信号的一种方法。它是一种调整最大值和最小值的方法，同时保持恒定频率并输出它们。

PWM信号使用数字信号之间称为占空比的比率表示模拟信号，而占空比表示高和低状态交替出现的时间之比。

PWM用于电源转换电路，电动机控制，LED调光和许多其他应用。

例如，在电机控制中，PWM用于控制电动机的速度和方向。

通过使用PWM，可以定期打开/关闭电动机的电压来控制电动机的旋转速度。

PWM也广泛用于LED照明中。通过控制使用PWM施加到LED的电压，可以调整LED的亮度。

因此，“电子组件PWM”是使用数字信号模仿模拟信号的方法之一，并且是在各种领域中使用的技术，例如电源转换电路，电动机控制和LED调光。
