Inductor and converter having the same

A converter, comprising an inductor having a current sampling function, wherein the converter is configured to obtain a current detection signal of the converter by a sampling part of the inductor, and the inductor comprises:

• a magnetic core comprising at least one window;
• and
• at least one winding provided within the at least one window, wherein the at least one winding comprises a main body part and the sampling part, the main body part has a first end and a second end, the sampling part has a first end and a second end, the first end of the sampling part is connected to the second end of the main body part such that 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,
• wherein the inductor further comprises a first sampling terminal and a second sampling terminal, the first sampling terminal is connected to the second end of the main body part or the first end of the sampling part, the second sampling terminal is connected to the second end of the sampling part, and the current flowing through the inductor is sampled by the first sampling terminal and second sampling terminal, and
• wherein the inductor further comprises a first inductive terminal provided at the first end of the main body part, wherein the second sampling terminal also functions as a second inductive terminal, and the second sampling terminal and the second inductive terminal are the same terminal, have the same size and are commonly used.
