The project is about developing an Arduino based AC motor control. In a previous project I have tried to use the Arduino to generate a PWM signal, that is later on filtered and amplified to generate a proper sine wave, that can be altered by frequency and amplitude to control a motor. Unfortunately with the current code it turned out, that the Arduino is not able to generate a stable sine, that will keep frequency and amplitude on a constant level over a longer amount of time - for several hours, but ideally as long as the Arduino is powered up. In a first step the given code shall be reviewed and optimized, to keep the PWM/sine signal stable. If necessary a new approach has to be found (based on the Arduino). The project will require availability of at least an oscilloscope, multimeter and an Arduino Uno board.

Frequency of the signal generated by Arduino should be enough stable. If you need a stable amplitude - I would propose to use a feedback (voltage measurement) to adjust it. But Arduino's built-in ADC has a very low precision, so external ADC may be necessary. I have all equipment that is necessary for prototyping and testing I work with Arduino since 2010 and have more than 20 years of experience in programming and electronics.

Hi, I'm Ganapathy Mechatronics engineer having experience in embedded and Power electronics I'm interested in your project , what your code lack is a feed control the output waveform deforms with the load variation ,so you need to measure the output voltage and output current and use a PID to correct the distortion of output If you interested contact me thank you

Hello Dear Employer, I am an expert in Arduino. I am experienced with similar project as you need. Please check my portfolio. You can found it in my profile. I used here PWM signal. Then filter it by a LC circuit. The output is a pure sine wave. Please check this.
