Coiled power device comprising a winding of a first coiling and a winding of a second coiling which cover the same portion of a magnetic core member

摘要

A coiled power device including a magnetic core including a first leg and a second leg which are parallel to each other, the device including a first coil and a second coil to generate mutual inductance between the coils, the first coil including a first winding of conducting wires around the first leg and a second winding of conducting wires around the second leg, the second coil including at least a third winding of conducting wires around the second leg and a fourth winding of conducting wires around the first leg, the first winding and the fourth winding covering the same portion of the first leg to limit leakage inductance of the coiled power device.

1. A coiled power device comprising:
a magnetic core comprising at least a first leg and a second leg which are parallel to each other; a first coil and a second coil to generate mutual inductance between the coils; wherein the first coil comprises at least a first winding of conducting wires around the first leg and at least a second winding of conducting wires around the second leg which is connected to the first winding, a free end of the first winding forming a first input terminal and a free end of the second winding forming an output terminal; the second coil comprises at least a third winding of conducting wires around the second leg and at least a fourth winding of conducting wires around the first leg which is connected to the third winding, a free end of the third winding forming a second input terminal and the free end of the fourth winding being connected to the output terminal; the first winding and the fourth winding cover a same portion of the first leg to limit leakage inductance of the coiled power device; and each winding comprises at least two layers of turns, the layers of the first winding being alternated with the layers of the fourth winding on the first leg.
