Two Methods to SVPWM Harmonic Analysis and the Essential Relation

Abstract:

Aiming at the problem of the harmonic of the space vector pulse width modulation (SVPWM), the analysis methods to SVPWM are studied. After introducing the principle of SVPWM, the paper discusses the harmonic distortion factor (HDF) that is an important assessing index of the harmonics. The two analysis methods- ripple current method and error triangle method – are discussed, and the relation between them is revealed. Finally, the micro HDF of the random zero distribution PWM (RZDPWM) is computed based on the two methods and analyzed.
