Hello,
Someone can help me to write a code for VFD using Atmega32

I am using sine wave samples array & timers 0, 1AL & 2 of the microcontroller to get 3-phase PWM gate signal. What modifications I have to do to change it for VFD (Frequency varying from 0-50 Hz) by keeping V/f ratio constant. I want to use a simple potentiometer externally to change the speed of 3-phase induction motor.
I should be very thankful to you in this regard. Thanks
