A novel approach to eliminate zero-sequence harmonics current

APCCAS 2008 - 2008 IEEE Asia Pacific Conference on Circuits and Systems, 2008
Zero-sequence harmonics caused by nonlinear loads usually result in high voltage distortion levels throughout the facility, neutral conductor overloading, motor heating, transformer heating, increased losses, and excessive harmonic injection onto the utility supply system. This paper presents a novel method to eliminate zero-sequence harmonics by using
