    摘要： A coupled inductor includes a ladder magnetic core including (a) a first rail and a second rail separated from each other in a first direction and (b) a plurality of rungs separated from each other in a second direction. The second direction is orthogonal to the first direction, and each rung of the plurality of rungs is disposed between the first rail and the second rail in the first direction. The coupled inductor further includes a plurality of windings, where each winding of the plurality of windings is partially wound around a respective one of the plurality of rungs such that each winding of the plurality of windings does not overlap with itself when the coupled inductor is viewed cross-sectionally in a third direction. The third direction is orthogonal to each of the first direction and the second direction.

    摘要： A multi-level switching power converter includes a string of N upper transistors and a string of N lower transistors, where N is an integer greater than one. The N upper transistors are electrically coupled in series between a first power node and a switching node, and the N lower transistors are electrically coupled in series between the switching node and a reference node. The multi-level switching power converter further includes N−1 flying capacitors, an inductor, a bypass transistor, and a controller. The bypass transistor is electrically coupled between the switching node and the reference node. The controller is configured to (a) control switching of the N upper transistors and the N lower transistors and (b) cause the bypass transistor to operate in its on state in response to all of the N lower transistors operating in their respective on states.

    摘要： A method for controlling a switching circuit including an input port electrically coupled to a photovoltaic device and an output port electrically coupled to a load includes (1) entering a voltage limiting operating mode and (2) in the voltage limiting operating mode (i) causing a control switching device of the switching circuit to repeatedly switch between its conductive and non-conductive states in a manner which limits magnitude of an output voltage to a maximum voltage value, the output voltage being a voltage across the output port, and (ii) varying the maximum voltage value as a function of magnitude of an output current, the output current being a current flowing through the output port.
