Signal harmonics presence in a power system is a major concerned to power engineers for many years. With increasing use of nonlinear loads in power systems, the harmonic pollution becomes more serious. One of the widely used computation algorithm for harmonic analysis is fast Fourier transform (FFT). In this paper, a harmonic analyzer using FFT was implemented on TMS320C6713 DSK. Here, two tests were conducted in order to analyze the harmonic content of 240V, 50Hz power supply. First, the supply voltage is stepped down to 5V using a voltage divider in order to match the power rating of the DSK input. Secondly, the supply voltage is stepped down using a step-down transformer. The output from the DSK was displayed on oscilloscope and Code Composer Studio Software. This work has demonstrated the possibility of analyzing the 240V power supply harmonic content using the DSK board. © 2009 IEEE.
