20160094218 | CASCODE TRANSISTOR CIRCUIT - A cascode transistor circuit comprising a depletion-mode switch in series with a normally-off switch between a drain output terminal and a source output terminal. The circuit also includes a controller comprising a controller output terminal configured to provide a normally-on control signal for a normally-on control terminal of the depletion-mode switch, wherein the normally-on control signal is independent of the normally-off control signal; a negative voltage source configured to provide a negative voltage to the normally-on control terminal of the depletion-mode switch; and a feedback capacitance between the drain output terminal and a control node in a circuit path between the controller output terminal and the normally-on control terminal of the depletion-mode switch. | 03-31-2016 |

20110031816 | PHOTOVOLTAIC UNIT, A DC-DC CONVERTER THEREFOR, AND A METHOD OF OPERATING THE SAME - A photovoltaic unit is disclosed comprising a plurality of sub-units connected in series, each sub-unit having a main input and a main output, which main output is connected to the respective main input of a neighbouring sub-unit, each sub-unit further comprising a segment comprising one or more series-connected solar cells, and a supplementary power unit, wherein the supplementary power unit is configured to at least one of receive power from or supply power to the neighbouring sub-unit. The supplementary power unit is preferably a DC-DC converter, and arranged to exchange energy between neighbouring segments, without requiring a high-voltage connection across the complete string (of more than 2 segments). The converter may be inductive or capacitive. | 02-10-2011 |

20110115297 | PHOTOVOLTAIC ASSEMBLY AND METHOD OF OPERATING A PHOTOVOLTAIC ASSEMBLY - A photovoltaic assembly is disclosed which comprises a string formed from a plurality of series-connected photovoltaic generators, and a hierarchical structure of power-exchange units, which each exchange power between neighbouring photovoltaic generators or groups of photovoltaic generators. | 05-19-2011 |
20120098344 | PHOTOVOLTAIC UNITS, METHODS OF OPERATING PHOTOVOLTAIC UNITS AND CONTROLLERS THEREFOR - The present invention relates to the field of photovoltaic systems with solar cell (s) or modules having insolation differences or mismatch. Each solar module is formed by placing a large number of solar cells in series. The PV system is then formed by placing a number of solar modules in series in a string and sometimes by placing multiple strings of series-connected solar modules in parallel, depending on the desired output voltage and power range of the PV system. In practical cases, differences will exist between output powers of the solar cells in the various modules, e.g. due to (part of) the modules being temporarily shaded, pollution on one or more solar cells, or even spread in solar-cell behaviour that may become worse during aging. Due to the current-source-type behaviour of solar cells and their series connection these differences will lead to a relatively large drop in output power coming from the PV system. This invention addresses this problem by adding DC-DC converters ( | 04-26-2012 |
