Abstract
A power converter comprises a buck converter portion, an energy storage portion, and a controller. A first inductor is connected between the cathode of a first diode at an input node, and a capacitor at an output node. The input node is connected to an input voltage via a first switch. A second inductor in the energy storage portion is magnetically coupled to the first inductor and is connected to a second diode. The cathode of the second diode is connected to a first terminal of the energy storage element, and a second terminal of the energy storage element is connected to a second terminal of the second inductor. The first terminal of the energy storage element is connected to the input node via a second switch. When the input voltage is not less than a threshold, the second switch is opened.
