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 ...

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 ...

This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

The main focus of this project is to create extra channels of 16-bit PWM in the MCU using the available 4 channels of 8-bit PWM on ATmega328P. This is important because high-resolution PWM is ...

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 ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

A pulse-width-modulated (PWM) signal and the RC-charging characteristics of a weighted-capacitor network can be used along with a CMOS Schmitt inverter to generate a pulse whose width is linearly ...

In exploring the use of analogWrite() and digitalWrite() on the Raspberry Pi Pico using Arduino, I have discovered some strange behaviors when switching between those modes on the same GPIO pin. This ...
