PWM的应用可以说非常广泛，比如在控制电机速度、灯光亮度、通信调制等众多领域都比较常见。 关于PWM的问题，通常小伙伴问的比较多。正好我最近也在用PWM，所以今天就分享一下关于PWM的常见方法和注意事项。 什么是PWM？ PWM：Pulse Width Modulation，脉冲宽度调制。

本文介绍一款简单、可重复且高精度的PWM驱动16位DAC设计，涵盖滤波器、OP与误差控制方法... 通过将单个脉冲宽度调制器(PWM)与模拟低通滤波器串接，以实现简单的数模转换器(DAC)，这并不是什么新鲜事了。将最最高有效位2 N PWM输出与最低有效位2 N PWM输出相加 ...

Mechanical relays continue to enjoy a growing demand and so far can't be replaced by solid state relays (SSR). Compared to SSRs, the lower cost, contact resistance and the galvanic isolation of ...

Relays and solenoids are available with many different voltage ratings. Most factory- and process-automation equipment operates from 24-V supplies. However, customers may have control signals for a ...

Proper thermal dissipation is an essential rule for nowadays electronics. The best operating temperature for the electronic components is 25 degrees (standard room temperature). Thermal dissipation in ...
