Abstract
The present disclosure discloses an inductor and a converter having the same. The inductor includes a magnetic core and a winding, the winding is provided within a window of the magnetic core, the winding includes a main body part and a sampling part, the main body part and the sampling part are connected in series, and a length ratio of the sampling part to the main body part is less than 2; wherein the main body part is formed of a low resistivity conductive material, the sampling part is formed of a low temperature coefficient conductive material, and a current flowing through the inductor is sampled across two ends of the sampling part. The inductor can obtain a current detection signal with high accuracy and low temperature drift with a compact structure, without increasing detection loss.
