<p>The present invention relates to a transformer and a power device. In the transformer having a sandwich wire structure, a noise of an opposite polarity transmitted to two wires surrounding both side of an output wire is combined to be neutralized and removed, thereby preventing the combination of an electrical noise with the output wire and greatly reducing the radiation of the noise through an output line, and saving the cost of an EMI filter.</p> |
