Abstract
A method of controlling a resolution of digital pulse width modulation is applied to a digital pulse width modulation generator. The method is to divide a value of a first duty clock by a value of a first pulse width modulation period clock to generate a first resolution. And then, if it is confirmed that a modulation command has been received, a second resolution is generated, and if it is confirmed that the modulation command is not received, a third resolution is generated. The second resolution is greater than the first resolution, and the second resolution is less than the third resolution.
