Hello!
I want to ask something about the Pulse Width Modulation. Which voltage value is more important? Average (V*duty) or RMS (V*sqrt(duty))? If I calculate the work, then the PWM's RMS value represents the equal DC voltage. By contrast every one uses the average voltage formula - etc. 10V, 50% PWM equals 5V DC.
What's the truth?
Best Regards
