Frequency and Total Harmonic Distortion Estimation Based on Adaptive Filters
(Institute of Electrical and Electronics Engineers, 2013-02)
In this paper, a low computacional cost total harmonic distortion and frecuency estimation method is proposed. This method is based on adaptive digital filters allowing tracking the fundamental frequency variations. Real ...
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 ...
