Classification: CPC H  Y | IPC H

Claim 9:
10. A two-way direct current (DC) converter circuit comprising:
a magnetic apparatus comprising:
a first magnetic member comprising:
a first magnetic cylinder;
a second magnetic cylinder;
a third magnetic cylinder; and
a fourth magnetic cylinder;

a first winding that is wound around the first magnetic cylinder and the second magnetic cylinder, wherein a first part of the first winding that is wound around the second magnetic cylinder forms a primary side resonant inductor, and wherein the first winding is wound around the second magnetic cylinder in a first direction;
a second winding that is wound around the first magnetic cylinder and the third magnetic cylinder, wherein a second part of the second winding that is wound around the third magnetic cylinder forms a secondary side resonant inductor, and wherein the second winding is wound around the third magnetic cylinder in a second direction that is opposite to the first direction; and
a second magnetic member configured to form, with the first magnetic member, a magnetic circuit of a transformer through the first magnetic cylinder and the fourth magnetic cylinder;

a primary side resonant switch circuit coupled to the primary side resonant inductor; and
a secondary side resonant switch circuit coupled to the secondary side resonant inductor.
