The invention relates to a method for generating an estimate of a switching instant in pulse-width modulation, wherein the switching instant corresponds to a point where the amplitude of a carrier signal Sc becomes greater than the amplitude of a input signal Sin. The method comprises the steps...
This paper reviews certain aspects of pulse-width modulation (PWM) and provides some new ideas and analyses. Computer simulations are used to study three-level PWM, the application of wide-band feedback from the unfiltered output stage, and dithering of the bias clock frequency. It is shown th...

Pulse-Width Modulation, or PWM, is one of the ways display makers can use to adjust the display's brightness. PWM is considered to be an easy (or cost-effective) way to control the brightness, but it has serious drawbacks, such as flicker that may cause eye strain and headaches. In th...
According to the pulse-width modulation (PWM) type built-in light adjustment power source of the utility model, a pulse-width modulation (PWM) light adjustment mode is adopted to make brightness variation of the LED lamp more uniform. The pulse-width modulation (PWM) type built-in light ...

Method and systems for high-precision pulse-width modulation In various embodiments, systems and methods for generating high-precision pulse-width modulation include a delay-locked loop comprising multiple delay units having time-variable delays, control logic for selecting a subset S of the multi......
Pulse Width Modulation (PWM) works by switching a digital signal between high (on) and low (off) states at a high frequency, creating a square wave. The duration for which the signal remains in the "on" state within each cycle, known as the duty cycle, determines the average power deliv...
