20140340062 | SINGLE-STAGE SOLAR-PHOTOVOLTAIC POWER CONVERSION CIRCUITRY - A DC-to-DC power converter includes an input to receive an input voltage and an input current from a solar panel, an output to provide an output voltage and an output current, and a single-stage switched-mode power-conversion circuit, coupled between the input and the output, to convert the input voltage and input current to the output voltage and output current in accordance with a control signal. The DC-to-DC power converter also includes a sense-and-control unit to sense the input voltage, input current, output voltage, and output current, and to generate the control signal based at least in part on one or more of the sensed input voltage, input current, output voltage, and output current. | 11-20-2014 |
