Real-Time Digital PWM With Zero Baseband Distortion and Low Switching Frequency
(Ieee-inst Electrical Electronics Engineers Inc, 2013-06)
A discrete-time pulse width modulator (PWM) with zero baseband distortion for arbitrary band-limited modulating signals is developed in this paper. It is based on adjusting the duty-cycles of the PWMsuch that the samples ...
Analysis of the Effectiveness on Reducing Welding Distortion of a Low Transformation Temperature Weld Wire

Reduction of total harmonic distortion in power inverters
(Planta Piloto de Ingeniería Química, 2005-12)
The output voltage of PWM power inverters shows harmonic distortion due to several causes; the main ones are the modulation algorithm, nonlinearities in the output filter, dead times, voltage drops across the switches and ...
Modeling, estimating, and compensating low-bit rate coding distortion in speech recognition
(2006)
A solution to the problem of speech recognition with signals distorted by low-bit rate coders is presented in this paper. A model for the coding-decoding distortion, a HMM compensation method to include this model, and an ...
Real-time low-distortion digital PWM modulator for switching converters
(Praise Worthy Prize, 2012-10)
A compensation scheme to reduce the inherent baseband distortion in uniform PWM modulators (UPWM) is presented in this paper. The method is based on real-time mapping of the switching times of UPWM to those of natural PWM ...
Digital Distortion-Free PWM and Click Modulation
(Institute of Electrical and Electronics Engineers, 2018-03)
This brief exhibits the relationship between the analog click modulator, which produces a binary pulse width modulation (PWM) signal with separated baseband, and recently reported fully digital, baseband distortion-free ...
