Pulse Width Modulated Inverter Model. High Voltage Inverter Design Along with the wider application of PWM technology used in inverting and the inverse frequency fields, as well as the rapid development of IGBT, MOSFET and other power switching device of such PWM control of high-voltage power supply toward miniaturization, high frequency, intelligent, high efficiency direction. The Arduino's programming language makes PWM easy to use; simply call analogWrite(pin, dutyCycle), where dutyCycle is a value from 0 to 255, and pin is one of the PWM pins (3, 5, 6, 9, 10, or 11). Three-Level PWM DC/AC Inverter Using a Microcontroller Oliver Rich William Chapman MQP Terms A-B-C 2011-2012 Advisor: Professor Stephen J. I want to design pure sine wave inverter using Arduino I found the code of pure sine wave inverter using pic microcontroller but I need code with arduino. PWM or Pulse Width Modulation is the technology to generate a steady output voltage from inverters. Because Arduino Uno does not have analog output, the PWM output is used with corresponding RC filter. The photo-sensor detects the reflected IR LED light by dust particles in air.
