Pure sine wave inverter using sPWM signal generated from arduino
Micro grid tied inverter. Arduino based, aimed for individual solar panel use.
The term SPWM stands for “Sinusoidal pulse width modulation” is a technique of pulse width modulation used in inverters. An inverter generates an output of AC voltage from an input of DC with the help of switching circuits to reproduce a sine wave by generating one or more square pulses of voltage per half cycle.
Examples for Arduino SPWM and Pure Sine Wave Generation
This Project tries to produce a sine wave output of an inverter using analog devices instead of conventional microcontrollers.
