Abstract
A magnetic component comprising: a magnetic core comprising an upper magnetic core portion, a lower magnetic core portion, and four core columns; a first winding wound around any two core columns which form a first closed magnetic circuit with the upper and lower magnetic core portions therebetween; and a second winding wound around remaining two core columns which form a second closed magnetic circuit with the upper and lower magnetic core portions therebetween. A sum of an AC flux peak-peak value within single core column of the first closed magnetic circuit, and an AC flux peak-peak value within single core column of the second closed magnetic circuit is larger than not only an AC flux peak-peak value within the upper magnetic core portion, but also an AC flux peak-peak value within the lower magnetic core portion. The first winding and the second winding are not connected in series directly.
