Harmonic and Loss Analysis of Space-Vector Modulated Converters

چکیده
Space Vector Modulation (SVM) is an alternative method to the conventional, sinusoidal PWM for control of highpower converters. It is known for its higher utilization of the dcbus voltage as well as being readily available for digital implementation. This paper presents the SVM method and a number of its variations, which are implemented in a digital transient simulation program (PSCAD/EMTDC). The developed model is used to study the performance of SVM in terms of its harmonic spectrum and associated losses. These factors are compared against different SVM implementations as well as the sinusoidal PWM strategy. The suitability of the model is hence ascertained. Keywords—Harmonic analysis, space-vector modulation, switching losses, transient simulation, voltage-sourced converter.
