摘要：
Inrush current is an important issue for transformers security and stability. Harmonic effects in power systems have been significantly increasing in the last decade. In this paper, SINm(omega t) waveforms represent non-sinusoidal waveforms because studies on SINm(omega t) waveforms appear to be simpler for more predictable results. A flux analysis of single-phase transformer is proposed in this paper. Furthermore, an active suppression method of inrush current is proposed. Finally, the effect of non-sinusoidal excitation to inrush current is analyzed and discussed in detail.
