误差自校正互补非零矢量相电流重构研究
Research on Phase Current Reconstruction of Error Self-correction Complementary Non-zero Vector
摘要
Abstract
Aimed at the problems of current unobservable area and zero drift error in the traditional space vector pulse width modulation with single-sensor phase current reconstruction method,an error self-correction complementary non-zero vector pulse width modulation method is proposed.Through the analysis of the DC bus sample principle,the minimum sample time is defined,the complementary non-zero vector is used to replace the zero voltage vector,and the current sampling window is extended,thus eliminating the sector boundary unobservable area.At the same time,the generation mechanism of error amplification effect is revealed,and the zero drift is detected and self-corrected by means of double-sampling complementary non-zero vector,which realizes the compensation for current zero drift reconstruction.Experimental results show that the reconstruction error of the proposed method was lower than 1.26%,and the phase current THD was lower than 6.15%.关键词
