| Abstract: | Based on the morphological wavelet of current,the model of the early detection at the short circuit fault was built, then the hardware circuit of the early detection at the short circuit fault was designed based on the TMS320F2812. The morphological filter and cubic B spline arithmetic were used to realize the fast and accurate judgement at the short circuit fault. This method lays the foundation for fast disconnecting the failure circuit. |
