WebAbstract: Constant-frequency pulsewidth modulation (PWM) is the most frequently used method in the control of switching converters. This paper proposes a general PWM modulator that realizes various control schemes with either trailing-edge or leading-edge modulation. Based on that a general double-edge modulator ran be constructed.

Three types of pulse-width modulation (PWM) are possible: The pulse center may be fixed in the center of the time window and both edges of the pulse moved to compress or expand the width. The lead edge can be held at the lead edge of the window and the tail edge modulated. The tail edge can be … Meer weergeven Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a method of controlling the average power delivered by an electrical signal.
