WebIn the early decades, when all audio equipment produced several per cent distortion, the THD figure told you something about how it might sound. Today, with low-fi car stereos producing less than 0.01% distortion, the specification no longer has any meaning. WebThe characteristic rise in published THD curves at power levels below about 1 watt is almost * entirely * due to supply frequency hum and wide band random noise. NOT any mysterious x-over region effects !!!!! The general definition of THD *** includes *** hum and noise - which tends to be a fixed level at all power outputs. WebOn the contrary, the traditional direct AC/AC voltage controllers, as well as frequency changers, suffer from high total harmonic distortion (THD) problems. In this paper, a new single-phase to three-phase AC/AC step-down power converter is proposed, which utilizes a multi-linking transformer and bilateral triode thyristors (TRIACs) as power semiconductor … chelsea maple residences phase 1
