TECHNIQUES FOR GRID COUPLING PHOTOVOLTAIC CELLS USING RATIOMETRIC VOLTAGE CONVERSION
摘要
<p>Techniques for electrical power transfer in photovoltaic systems are provided. In one aspect, a photovoltaic system includes an array of photovoltaic power producing elements (e.g., concentrator photovoltaic cells); a power receiving unit; and at least one ratiometric DC to DC converter connected to both the array of photovoltaic power producing elements and the power receiving unit. The array of photovoltaic power producing elements can include a plurality of the photovoltaic power producing elements connected in series or in parallel. In another aspect, a method of transferring electrical power from an array of photovoltaic power producing elements to a power receiving unit includes the following step. At least one ratiometric DC to DC converter is connected to both the array of photovoltaic power producing elements and the power receiving unit. The at least one ratiometric DC to DC converter is configured to alter a voltage output from the array.</p>
