【Abstract】 Minimum switch loss space vector modulation (MSL SVM) technique is a kind of switch modulating strategy in wide use. In this paper, the explicit modulated waves of several usual kinds of MSL SVM methods are attained and the qualitative harmonic analysis of those is done. According to the phase voltage modulated function, the mathematics model in frequency domain of the MSL SVM is derived by dual Fourier transform. On the basis of the analysis above, the quantitative mathematics analyses of the harmonic characteristic of MSL SVM are performed. Some conclusions are drawn that are of much importance to do further study of the input/output relationship and transmitting band of MSL SVM. Theoretical analysis is validated by simulation and experiment.更多还原
