摘要： A method for controlling a number of phases that are active in a multiphase direct-current-to-direct-current (DC-to-DC) converter includes (a) filtering a current signal representing a magnitude of current processed by the multiphase DC-to-DC converter to generate a filtered signal, (b) comparing the filtered signal to a first threshold value, (c) deactivating one or more phases of the multiphase DC-to-DC converter in response to the filtered signal falling below the first threshold value, (d) comparing the current signal to a second threshold value, the second threshold value being greater than the first threshold value, and (e) activating one or more phases of the multiphase DC-to-DC converter in response to the current signal rising above the second threshold value.

摘要： A method for testing a photovoltaic device electrically coupled to an input port of a maximum power point tracking (MPPT) controller, where the MPPT controller includes a switching circuit adapted to transfer power between the input port and an output port of the MPPT controller, includes the steps of: (a) driving a test current into the output port of the MPPT controller; (b) detecting presence of the test current; and (c) in response to detecting presence of the test current, causing the switching circuit to provide a path for the test current from the output port to the photovoltaic device.

摘要： A switching circuit for extracting power from an electric power source includes (1) an input port for electrically coupling to the electric power source, (2) an output port for electrically coupling to a load, (3) a first switching device configured to switch between its conductive state and its non-conductive state to transfer power from the input port to the output port, (4) an intermediate switching node that transitions between at least two different voltage levels at least in part due to the first switching device switching between its conductive state and its non-conductive state, and (5) a controller for controlling the first switching device to maximize an average value of a voltage at the intermediate switching node.

摘要： A regulated, power supply system is described using multiphase DC-DC converters with dynamic fast-turnon, slow-turnoff phase shedding, early phase turn-on, and both load-voltage and drive-transistor feedback to pulsewidth modulators to provide fast response to load transients. In an embodiment, a system master can automatically determine whether all, or only some, slave phase units are fully populated. The programmable system includes fault detection with current and voltage sensing, telemetry capability, and automatic shutdown capability. In an embodiment, these are buck-type converters with or without coupled inductors, however some of the embodiments illustrated include boost configurations.

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.

摘要： An electric power system includes N electric power sources and N switching circuits, where N is an integer greater than one. 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.
