According to the present disclosure, a filter for reducing electromagnetic noise discharged through a line connected to the positive terminal B(+) of the battery is designed, but there is a problem that noise is rather introduced through this filter. However, in the filter circuit of the present disclosure, noise reversely introduced through the filter may be blocked by arranging an inductor for the filter in an expected inflow path of noise.
