Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an
An Arduino-compatible board designed for auto-piloting and autonomous navigation of aircraft, cars, and boats. It uses GPS for navigation and thermopile sensors or an IMU for stabilization. ArduIMU [142] An Arduino-compatible board designed for inertial measurement and inertial navigation of aircraft, cars, and boats.
PWM output (some devices have an enhanced PWM peripheral which includes a dead-time generator) Input capture that record a time stamp triggered by a signal edge; Analog comparator; 10 or 12-bit A/D converters, with multiplex of up to 16 channels; 12-bit D/A converters; A variety of serial interfaces, including I²C compatible Two-Wire Interface ...
Space vector modulation (SVM) is an algorithm for the control of pulse-width modulation (PWM), invented by Gerhard Pfaff, Alois Weschta, and Albert Wick in 1982. [1] [2] It is used for the creation of alternating current (AC) waveforms; most commonly to drive 3 phase AC powered motors at varying speeds from DC using multiple class-D amplifiers.
It is analogous to pulse-width modulation (PWM), in which the magnitude of an analog signal is encoded in the duty cycle of a square wave. Unlike PWM, in which the width of square pulses is varied at a constant frequency, PFM fixes the width of square pulses while varying the frequency.
Electromagnetic interference (EMI) filters have been widely used for filtering out the conducted emissions generated by power converters since their advent. However, when size is of great concern like in aircraft and automobile applications, one of the practical solutions to suppress conducted emissions is to use random pulse-width modulation (RPWM).
Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
The Netduino family is based on the Cortex-M Micro Processor running the .NET Micro Framework (NETMF) v4.3. [6] Development can be done on both Windows, with Visual Studio, or with Xamarin Studio on Mac OS X. IO includes 22 General Purpose Input/Output (GPIO) ports, 6 of which support hardware Pulse Width Modulation (PWM) generation, 4 UARTs (serial communication), I2C, and SPI (Serial ...
