1. An integrated magnetic element, comprising:
an accommodating part;
a current sensor disposed on the accommodating part; and
a transformer disposed on the accommodating part, the transformer comprising a magnetic core, a first winding and a second winding, wherein the first winding comprising a plurality of first ends and second ends, the plurality of first ends formed by a plurality of wires, one first end formed by one wire, wherein the plurality of wires are connected in parallel, at least one but not all of the plurality of wires passes through the current sensor in order to detect a current value flowing through the at least one but not all of the plurality of wires, and a total current value of the first winding is obtained according to a shunt ratio.
