- Maximum PWM frequency is limited by:
- turn-on and turn-off delays times (this would limit the frequency at about 3kHz)
- hearable audio range (1-16kHz) - these frequencies produce a buzzing sound that is very unpleasant for the human ear and are because of that avoided
- As a result of calculations and measurement, it is proven that the higher the frequency the smaller the duty cycle can be.
