Microinverters for employment in connection with photovoltaic modules
| DWPI Title: Solar power system for providing electric power to residence by utilizing fossil fuels in electric power system, has photovoltaic module including first and second microinverters that are electrically connected in parallel and interleaved |
| Abstract: Microinverters useable in association with photovoltaic modules are described. A three phase-microinverter receives direct current output generated by a microsystems-enabled photovoltaic cell and converts such direct current output into three-phase alternating current out. The three-phase microinverter is interleaved with other three-phase-microinverters, wherein such microinverters are integrated in a photovoltaic module with the microsystems-enabled photovoltaic cell. |
| Use: Solar power system for providing electric power to a residence by utilizing fossil fuels in an electric power system. |
| Advantage: The system allows capacitance of a capacitor to be selected based on a threshold of acceptable ripple losses, thus increasing output current by an overall function of a control system when voltage of the photovoltaic module is above a module maximum power point and decrease the output current when the voltage of the photovoltaic module is below the module maximum power point, and hence creating a string of the photovoltaic cells electrically connected in series in a relatively small amount of space. The system provides a more precise voltage match. |
| Novelty: The system (300) has a photovoltaic module (308) including first and second microinverters (302, 304) that are electrically coupled to first and second solar cells, respectively, where the first and second microinverters convert first and second direct current outputs generated by the first and second solar cells to first and second three-phase alternating current outputs, respectively. The first and second microinverters are electrically connected in parallel, where the first and second microinverters are interleaved. The solar cells are micro-system enabled photovoltaic (MEPV) cells. |
