摘要
En 中文
This paper describes a novel switching signal generator for three-phase voltage source inverters. Unlike conventional space-vector pulsewidth modulation (SVPWM) which achieves three-phase input voltage by a combination of the basic space vectors, the proposed scheme produces optimal switching commands to minimize the filtered measure of quantization error. Under specific selections of the filter matrix and the quantization scheme, it is shown that the proposed modulator is equivalent to SVPWM. An experimental platform is built to verify the effectiveness of the proposed scheme. It is shown that the switching number of the proposed method is reduced without sacrificing the harmonic distortion within the input frequency band under various reference signals.
