Abstract

This paper presents a SVM implementation based on simplified decision trees (SDT). SDT-SVM applies SDT to the calculation of sector index and the duration of the adjacent switching state vectors, by which the none-linear calculations such as sin, atan and sqrt functions are avoided. This technique can be realized easily and reduces the computation time and improves the accuracy markedly. Further more, the sample time can be shortened in this case, which can reduce the total harmonic distortion (THD) and make the output waveform better.
