Abstract
One example of a device includes an output terminal to electrically couple to a load, a first input terminal to electrically couple to a first voltage source, and a blocking rectifier electrically coupled between the first input terminal and the output terminal. The device includes a second input terminal to electrically couple to a second voltage source. The second input terminal is electrically coupled to the output terminal. The device includes a control circuit to control the second voltage source to prevent a voltage at the output terminal from exceeding a voltage at the first input terminal and to deliver power to the load in place of power delivered by the first voltage source.
