Magnetic component, power conversion apparatus, and power conversion system

A magnetic component comprising:

• a magnetic core including two base parts opposed to each other, and six leg parts disposed within opposed surfaces of the two base parts and magnetically coupling the two base parts, the six leg parts including a first leg part, a second leg part, a third leg part, a fourth leg part, a fifth leg part, and a sixth leg part, the first leg part, the second leg part, and the third leg part being arranged side by side in this order in a first direction, the fourth leg part, the fifth leg part, and the sixth leg part being arranged side by side in this order in the first direction, the first leg part and the fourth leg part being arranged side by side in a second direction, the second leg part and the fifth leg part being arranged side by side in the second direction, the third leg part and the sixth leg part being arranged side by side in the second direction;
• a first coupling terminal and a second coupling terminal;
• a first winding that is, in a direction from the first coupling terminal to the second coupling terminal, wound around the first leg part, the third leg part, and the fifth leg part in a first winding direction, and around the second leg part, the fourth leg part, and the sixth leg part in a second winding direction;
• and
• one or multiple second windings wound around four of the six leg parts other than the first leg part and the sixth leg part.
