Reduction of total harmonic distortion in power inverters [PDF]
, 2005 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 modulation of the dc bus voltage.

Thd Analysis Of Lfac Transmission System
, 2015 This paper deals with the design of filters and THD analysis of a low - frequency ac (20Hz) transmission system. The LFAC system is interfaced with the 50Hz main power grid with a cycloconverter. The wind power is collected in dc form,and is connected to the L FAC transmission line with a twelve pulse inverter.

THD Doppler procedure for hemorrhoids: the surgical technique [PDF]
Techniques in Coloproctology, 2013 Abstract Transanal hemorrhoidal dearterialization (THD) is an effective treatment for hemorrhoidal disease. The ligation of hemorrhoidal arteries (called “dearterialization”) can provide a significant reduction of the arterial overflow to the hemorrhoidal piles.
