Abstract
A bi-directional DC-to-DC power converter is provided. The power converter has three modes of operation: (1) a step-down mode, in which the power converter converts power in a first direction (such as from a high-voltage power bus to a low-voltage power bus), and (2) a step-up mode, in which the power converter converts power in the opposite direction (such as from the low-voltage power bus to the high-voltage power bus), and (3) an off mode, in which no power is transferred. A single power converter may therefore be used to replace both a conventional step-down converter and a conventional step-up converter. The power converter may provide a battery charge-control functionality, and may be used to charge a battery that may, for example, provide a source of power to a component of an electrical device.
