Abstract
A power converter and methods with an input terminal, a capacitor, a first output terminal, a second output terminal, an output switch between the first output terminal and the second output terminal, and an inductor are presented. A first terminal of the inductor is connected to the first output terminal. An input switch is connected between the input terminal and a first terminal of the capacitor. A first capacitive charging switch is connected between the first terminal of the capacitor and the second output terminal. A second capacitive charging switch is connected between the second output terminal and a second terminal of the capacitor. A ground switch is connected between the second terminal of the capacitor and a reference potential. The power converter can convert electrical power into electrical power for powering an external device d or into electrical power for charging an external energy storage device.
