Abstract
An embodiment is an apparatus that includes an energy-storage circuit and a rectifying circuit. The energy-storage circuit is configured to generate a current that flows in a direction, and the rectifying circuit is configured to substantially block the current from flowing in a reverse direction in response to the current. Such an apparatus may be configured to block a reverse current before it begins to flow. For example, such an apparatus may include a transistor disposed in the path of the current, and may be configured to deactivate the transistor while a forward current is still flowing. Furthermore, by being configured to block the current from flowing in a reverse direction in response to the current itself, such an apparatus may better block a reverse current than an apparatus that blocks a reverse current in another manner, such as in response to a voltage across a rectifying transistor.
