LEDの明るさを変えたり、モーターの速さを調整したり。そんなときに使われるのが「PWM制御」という技術です。 この記事では、Raspberry Pi（ラズパイ）で使える2つのPWM制御方法「ソフトウェア制御」と「ハードウェア制御」について、初心者向けにわかり ...

IoT第3回です。 第1回：全体構成 第2回：GPIO 今日はPWMです。 第2章：部品をraspberry piから操作する仕組み～その②PWM～ 【理系の解説】 ラズベリーパイからIoT機器を制御するときに，機器への電圧をオン・オフの切替（パルス）で制御する方法をPWM制御と言う． ...

In LCD backlight applications, a dc-to-ac inverter drives cold-cathode fluorescent lamps. The inverter's input comes from the display's power supply. Currently, it spans from 12 to 18 V. Pulse-width ...

I have had an on-going mission to design a universal-ish pcb that will convert a PWM waveform at one frequency into to another frequency while retaining the mark-space ratio. The obvious answer is a ...

Pulse-width modulation (PWM) generators are integrated in nearly every switching power device. This article shows two methods for implementing a stand-alone analog PWM waveform generator. These ...

Pulse-width modulation (PWM) is an efficient method for controlling the light intensity of a lamp or the speed of a simple DC motor. It lets you take advantage of the load's inertia by switching the ...

Digital control of switch-mode power supplies (SMPSs) is becoming practical thanks to the evolution of low-cost, high-performance devices with peripherals designed for power-conversion applications.

Abstract: Due to the wide applications of DPWM (Digital Pulse Width Modulation) /DPFM (Digital Pulse Frequency Modulation) in the industry, a 4-bit Dual Mode (PWM/PFM) Digital Pulse Modulation (DMDPM) ...
