Space vector Fourier analysis of SVM inverters in the overmodulation range

Voltage-source inverters with space vector modulation (SVM) are largely adopted in power conversion for AC drives. In this context, the pulse-width control in the overmodulation range is becoming a topic of considerable interest. The paper proposes a novel application of the space vector Fourier analysis to the voltages produced by the SVM inverters operating in the overmodulation range. A direct derivation of the output voltage low-order harmonic content is given, and a unified and analytical comparison among different SVM inverter overmodulation strategies is enabled.
