Removable modular units with measurement capabilities are used in the combiner boxes to measure the direct current input provided by the strings; and in light of the measurements, the removable modular units can be selectively downgraded to simpler units that do not have measurement capabilities to reduce cost, and/or selectively upgraded to more sophisticated units that can adjust the output of the respective strings, such as upconverting the output voltage of the respective strings, to improve the performance of the strings. | 12-10-2015 |
20160036233 | SERIES-PARALLEL CONVERSION POWER DEVICE - A series-parallel conversion device includes n cell series connection units and a plurality of inter-unit connection switches. Each connection unit has n−1 cells and one intra-unit switch. The connection switches connect adjacent connection units. The connection units are disposed in parallel in n columns between a positive electrode terminal and a negative electrode terminal. The intra-unit switch in a cell series connection unit column has a first terminal and a second terminal. The first terminal is connected to a negative electrode terminal of a k-th cell from the negative electrode terminal or the positive electrode terminal. The second terminal is connected to a positive electrode terminal of a (k−1)-th cell from the negative electrode terminal or the negative electrode terminal. The connection switch is connected between the first terminal of the intra-unit switch of the k-th column and a second terminal of an intra-unit switch of a (k+1)-th column. | 02-04-2016 |
20160094038 | METHOD FOR USE OF STATIC INVERTERS IN VARIABLE ENERGY GENERATION ENVIRONMENTS - A method to collect energy from generation systems such as, for example, wind farms or solar farms with widely distributed energy-generation equipment. In some cases, static inverters are used to feed the energy directly into the power grid. In some other cases, back-to-back static inverters are used create a high-voltage DC transmission line to collect power from multiple generation sites into one feed-in site. | 03-31-2016 |
20160094073 | Cell Assembly having a Plurality of Electrochemical Cells and Method for Operating said Cell Assembly - A method includes activating electrochemical cells of a cell assembly to output electrical energy in accordance with a superordinate clock signal in order to have an activation and/or switch-off time points of the respective cells on the basis of the superordinate clock signal not all occur at the same time. To reduce the complexity of smoothing the total battery voltage, the switching time points according to the disclosure are shifted on the basis of the superordinate clock signal for the first cell in accordance with a first switching specification by a cell-specific first clock shift signal. | 03-31-2016 |
20160380430 | POWER SUPPLY APPARATUS - A power supply apparatus may include an electronic control unit. The electronic control unit may be configured to set target timing of switching of each of the switch. The electronic control unit may be configured to set the target timing in one cycle of a first carrier wave in accordance with first timing and in one cycle of a second carrier wave in accordance with second timing. The first timing may be two of timing in the one cycle of the first carrier wave that are defined by a first target duty ratio and the first carrier wave. The second timing may be two of timing in the one cycle of the second carrier wave that are defined by a second target duty ratio and the second carrier wave. The second carrier wave may be in the same cycle as the first carrier wave. | 12-29-2016 |
