    摘要： A regulated current-fed power system employs power branching units connected in series. Each power branching unit includes a plurality of parallel-redundant converter groups connected in series with each other within a current path for the regulated current. Each parallel-redundant converter group includes at least two direct current (DC)/DC converters connected in parallel with each other, each sharing the power load. A protection device connected in series with each DC/DC converter disconnects the respective DC/DC converter from the regulated current when the respective DC/DC converter short circuits, with the remaining DC/DC converter(s) then receiving more of the power load. An active clamp connected in parallel with all of the DC/DC converters within a parallel-redundant converter group temporarily sinks a portion of the regulated current when one of the DC/DC converters fails in a short-circuit condition. The active clamp shunts the regulated current around all DC/DC converters within the parallel-redundant converter group converters fail in a short-circuit condition.

    摘要： A solar array module system for generating electric-power, preconfigured to prevent electric blockage of the module when a physical row of solar cells malfunctions. The module includes a matrix of X physical rows and Y columns of solar cells, electrically interconnected in a plain criss-cross matrix. The columns of the physical matrix are divided into a first side, numbering YL columns, and a second side, numbering Y-YL columns. The first side includes cells that are physically inverted relative to the cells of the second side. The negative side of the cell in the 1+nth physical row of column YL is electrically connected to the negative side of the cell in the X-nth physical row of column YL+1 (0≤n

    摘要： Aspects of the disclosure provide a circuit that includes a switch control circuit and a timing control circuit. The switch control circuit is configured to enable/disable a pulse width modulation (PWM) switch control to a regulator to transfer power to a load. The timing control circuit is configured to enable an analog to digital converter (ADC) to convert an analog signal to a digital stream when the PWM switch control is disabled in order to reduce noise in the digital stream due to switching activities in the regulator.

    摘要： An operation mode selection unit selects an operation mode of a power converter and generates a mode selection signal indicating the result of selection, in accordance with a load condition and a power supply condition. An operation mode switching control unit generates a mode control signal designating an operation mode of the power converter. When the operation mode currently selected by the mode control signal is different from an operation mode indicated by the mode selection signal, the operation mode switching control unit adjusts a power distribution ratio between a plurality of DC power supplies or an output voltage on an electric power line so as not to change abruptly, and then permits a transition of operation mode.

    摘要： An electrical-energy harvesting system envisages a transducer for converting energy from an environmental energy source into a transduced signal, an electrical energy harvesting interface for receiving the transduced signal and for supplying a harvesting signal, and an energy storage element coupled to the electrical energy harvesting interface for receiving the harvesting signal. The electrical-energy harvesting system also includes a voltage converter connected to the electrical energy harvesting interface for generating a regulated voltage. The harvesting interface samples an open-circuit voltage value of the transduced signal, generates an optimized voltage value starting from the open-circuit voltage value, and generates an upper threshold voltage and a lower threshold voltage on the basis of the optimized voltage value. The harvesting interface controls the voltage converter in switching mode so that the harvesting signal has a value between the upper and lower threshold voltages in at least one operating condition.
