Abstract
Voltage waveform improvement has been the object of several investigations for many years and a manifold of different solutions have been proposed to reduce the harmonic content in Voltage Source Inverters (VSI) power application. In many cases this improvements have been obtained by modifying the reference voltage modulating signal. The recent introduction of cardinal B-spline functions, used as carrier signals, has given rise to a new modulation technique whose main characteristic is a lower value of the Total Harmonic Distortion (THD). After the discussion on the B-Spline modulation principle and on its computational effort, a performance comparisons is carried out by means of Total Harmonic Distortion (THD) index and single significant harmonics investigation of experimental data. All comparisons are carried out taking both the reference voltage and the Root Mean Square (RMS) values of the output voltage into account showing how these two choices leads to different conclusions in terms of performance.
