WebMay 28, 2013 · Thus, going back to definitions of “m” and “k”, we notice that by increasing turns ratio (n = Np/Ns) and increasing the delay time of the converter, we lower the THD. Besides these parameters, the EMI filter design also plays an important role in THD improvement. The three design considerations to lower the Total Harmonic Distortion: Calculating theoretical THD can be a good exercise, but it can be a lot of work, and in practice, you aren’t going to get an ideal signal (e.g., a perfect square wave) anyway. The outcome of these calculations can therefore only give an approximation for the THD that you might get for a given signal type. In practice, THD … See more Harmonics or harmonic frequencies of a periodic voltage or current are frequency components in the signal that are at integer multiples of the frequency of the main signal. This is the basic outcome that Fourier analysis … See more THD is defined as the ratio of the equivalent root mean square (RMS) voltage of all the harmonic frequencies (from the 2nd harmonic on) over the RMS voltage of the fundamental … See more This article has provided some background about THD and how to determine it, both theoretically and in a real (simulated) system.
