PWM (Pulse Width Modulation)or modulation with the width of an impulse, is a widespread term in the world of electrical engineering. It has a broad range of application, like in the field of telecommunications, audio equipment, servo motors, etc. Interesting for us enthusiasts is the applicatio...
The controller utilizes Infineon’s fast COT engine which simplifies the design efforts and achieves faster transient response. Fast COT control compares the output voltage to a floor voltage combined with an internal ramp signal. When Vout drops below that signal, a PWM signal is initiated to t...
One such term is the “photovoltaic effect.” Photovoltaic is often shortened to PV — as in PV panels. Photovoltaic is pivotal for harnessing solar energy. It holds the secret to converting sunlight into electrical power. Understanding how the PV effect works provides a clearer picture of th...
The VRM uses three components to complete its work: MOSFET, inductor (also called choke), and capacitor. There is also an integrated circuit (IC) for controlling all functions, sometimes referred to as a PWM controller. How Does VRM Improve Performance? VRM aims to provide clean and reliable ...
PWM stands for pulse width modulation. PWM fans and/or pumps are found in some CPU coolers and GPU (aka graphics card) coolers. They use an integrated circuit to control the speed of a fan or pump and, therefore, how much cooling it’s providing to the CPU or GPU. PWM fans and ...
How does it works ? A microcontroller processes data given to it’s input pins using it’s CPU and gives output via output pins. It executes or driven by asynchronous sequential logiccircuit. As per digital circuits theory, a sequential circuit is a logical circuit whose output not only depen...
Before we do a deep dive into how the VRM works, it is essential to understand what it is and what the term stands for. The term stands for“voltage regulator module”, andit describes an electronic circuit that regulates and converts voltages to meet the requirements of the CPU, memory,...
how to distinguish between 12:00 and 0:00 on an analog clock? That's a good one. And only too true :) The problem with PWM hardware is that it will usually be programmed to set and reset teh output at a certain moment. But what if the moment to set it is the moment to reset...
PWM frequency is15.625 kHz. How can microcontroller measure pulse width? First initializes ports and pins as input or output. Next it initializes LCD and displays message “frequency & pulse width measurement”. Then to calculate frequency it initializes timer 0 as counter to count external pulse...
What is Simulink Coder? Simulink Coder™ generates standalone C and C++ code from Simulink® and Stateflow® models for real-time and non-real-time execution. The generated code is ISO compliant, so it is portable and works with virtually any compiler or processor. The code can be depl...
