Abstract:
A core (X1) has a shape of a rectangular loop having sides (A1 to A4). The sides (A1, A3) are opposed to each other. The sides (A2, A4) are opposed to each other. A winding (w11) is wound around the core (X1) on the side (A2). A winding (w12) is wound around the core (X1) on the side (A4). A winding (w21) is wound around the core (X1) on the side (A2). A winding (w22) is wound around the core (X1) on the side (A4). The windings (w11, w12) are wound around the core (X1) at equal distances from the side (A1). The windings (w21, w22) are wound around the core (X1) at equal distances from the side (A1). The windings (w11, w12) are connected in series or in parallel to each other. The windings (w21, w22) are connected in series or in parallel to each other.
