Assignee: ACLEAP POWER INC.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An apparatus for DC-to-DC conversion, comprising:
a first transformer comprising a first winding at a primary side and a second winding at a secondary side;
a second transformer comprising a third winding at a primary side and a fourth winding at a secondary side; and
a controller configured to:
control a first current in the first winding of the first transformer and a second current in the third winding of the second transformer to flow in a first pattern, such that the second winding of the first transformer and the fourth winding of the second transformer are electrically coupled in serial to output a first voltage, and
control the first current and the second current to flow in a second pattern different from the first pattern, such that the second winding of the first transformer and the fourth winding of the second transformer are electrically coupled in parallel to output a second voltage lower than the first voltage,
wherein the controller is configured to control the first current and the second current to flow in different directions in the first pattern, and control the first current and the second current to flow in a same direction in the second pattern.
