PWM的应用可以说非常广泛，控制电机速度、灯光亮度、通信调制等众多领域。 PWM的问题小伙伴问的比较多，最近也在用PWM，这里就分享一下关于PWM的一些内容。 什么是PWM？ PWM：Pulse Width Modulation，脉冲宽度调制。 网上的解释很多，通过下图，你就能直观的理解 ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

脉宽调制（PWM），与其他效率较低的调制方法相比，它可以产生可变水平的功率。PWM的原理被用于许多应用中，例如电信，音频效果和照明，以及可通过微控制器生成PWM信号的电子设备。让我们看一下PWM的电子效应，以及如何最好地布置PWM微控制器的电路。

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

将PWM与一个小型R-2R梯形DAC相结合，既可大大减小PWM纹波，又能增加DAC分辨率，从而提高两方面的性能。本设计实例利用一个8电阻阵列和3个输出引脚对R-2R梯形DAC进行修改重构，修改的目的是将底部2R连接到PWM输出而不是将其接地。 将PWM和小型R-2R梯形DAC相结合 ...

The good thing about computers is they do your work for you, right? If you are a programmer, that doesn’t always seem to be a true statement. [Runtimemicro] has the answer, at least if you are writing ...
