摘要： Methods and structures for constructing a magnetic core of a coupled inductor. The method provides for constructing N-phase coupled inductors as both single and scalable magnetic structures, where N is an integer greater than 1. The method additionally describes how such a construction of the magnetic core may enhance the benefits of using the scalable N-phase coupled inductor. The first and second magnetic cores may be formed into shapes that, when coupled together, may form a single scalable magnetic core. For example, the cores can be fashioned into shapes such as a U, an I, an H, a ring, a rectangle, and a comb, that cooperatively form the single magnetic core.

摘要： Disclosed are systems, devices, circuits, components, mechanisms, and processes in which a switching mechanism can be coupled between components. The switching mechanism is configured to have an on state or an off state, where the on state allows current to pass along a current path. A monitoring mechanism has one or more sensing inputs coupled to sense an electrical characteristic at the current path. The electrical characteristic can be a current, voltage, and/or power by way of example. The monitoring mechanism is configured to output a reporting signal indicating the sensed electrical characteristic. The monitoring mechanism can be integrated with the switching mechanism on a chip.

摘要： An integrated circuit chip includes a first input port, a first output port, and first and second transistors electrically coupled in series across the first input port. The second transistor is also electrically coupled across the first output port and is adapted to provide a path for current flowing through the first output port when the first transistor is in its non-conductive state. The integrated circuit chip additionally includes first driver circuitry for driving gates of the first and second transistors to cause the transistors to switch between their conductive and non-conductive states. The integrated circuit chip further includes first controller circuitry for controlling the first driver circuitry such that the first and second transistors switch between their conductive and non-conductive states to at least substantially maximize an amount of electric power extracted from an electric power source electrically coupled to the first input port.

Each switching circuit includes an input port electrically coupled to a respective one of the N electric power sources, an output port, and a first switching device adapted to switch between its conductive and non-conductive states to transfer power from the input port to the output port. The output ports of the N switching circuits are electrically coupled in series and to a load to establish an output circuit. Each of the N switching circuits uses an interconnection inductance of the output circuit as a primary energy storage inductance of the switching circuit.

摘要： A maximum power point tracking controller includes an input port for electrically coupling to an electric power source, an output port for electrically coupling to a load, a control switching device, and a control subsystem. The control switching device is adapted to repeatedly switch between its conductive and non-conductive states to transfer power from the input port to the output port. The control subsystem is adapted to control switching of the control switching device to regulate a voltage across the input port, based at least in part on a signal representing current flowing out of the output port, to maximize a signal representing power out of the output port.
