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 ...
Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required ...
The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...
When designing a digital power supply such as boost power factor correction (PFC), have you ever seen a current oscillate like it does in Figure 1? You may think that this unstable oscillation is ...
