Abstract :
The authors present a simple method of finding the harmonic coefficient of a trigonometric Fourier series representation for signals which are defined over a finite range. This method can be used selectively to track any harmonic component or range of harmonic components of the signal. A matrix method has been developed which uses the least square (LSQ) criterion to approximate the given signal with that of the assumed Fourier series representation. The method can be used, in general, as a signal processing tool. For the purpose of illustration, a digital computer program is developed for selective harmonic tracking (SHT) of waveforms generated in multiple pulse converter systems connected to an HV AC system
