A magnetic apparatus includes a first magnetic member, a second magnetic member, a first winding, and a second winding, where the first magnetic member includes a first magnetic cylinder, a second magnetic cylinder, a third magnetic cylinder, and at least one fourth magnetic cylinder, and where the first winding is wound around the first magnetic cylinder and the second magnetic cylinder, the second winding is wound around the first magnetic cylinder and the third magnetic cylinder, and a direction in which the first winding is wound around the second magnetic cylinder is opposite to a direction in which the second winding is wound around the third magnetic cylinder.

Magnetic apparatus and two-way DC converter circuit

This application relates to the field of electronic technologies, and discloses a transformer and a power supply, to provide a magnetic cylinder distribution structure of a magnetic core while reducing a winding loss by using fractional turn, where the magnetic cylinder distribution structure of the magnetic core is conveniently to implement, thereby reducing product costs. The transformer includes a magnetic core, where the magnetic core includes a first magnetic cylinder and a second magnetic cylinder. One end of the first magnetic cylinder is coupled to one end of the second magnetic cylinder and the other end of the first magnetic cylinder is coupled to the other end of the second magnetic cylinder, to form an annulus.
