Abstract
Systems for converting a standard direct current (DC) power from solar panels into a rectified DC power signal for further conversion into alternating current (AC) power are described herein. In some example embodiments, the systems may include distributed power converters and a grid interface unit connected by a trunk cable. In some example embodiments, the power converters may be embedded in the trunk cable.
Claims18
A solar inverter system for converting direct current (DC) power from a plurality of photovoltaic modules into alternating current (AC) power, the solar inverter system comprising:
- a plurality of photovoltaic modules;
- a plurality of distributed power converters configured for being connected in series, wherein each of the distributed power converters is configured for being electrically connected to a respective photovoltaic module of the plurality of photovoltaic modules, and wherein each of the distributed power converters comprises a buck converter configured for converting a DC power signal received from the a respective photovoltaic module into a rectified sine wave signal;
- and
- a grid interface unit configured to be electrically connected to the power converters and to a power grid, wherein the grid interface unit is configured to convert the rectified sine wave signal produced by the plurality of converters to an AC signal for supply to the power grid;
- wherein each photovoltaic module of the plurality of photovoltaic modules is configured for being electrically connected to a respective distributed power converter of the plurality of distributed power converters, and wherein the photovoltaic modules of the plurality of photovoltaic modules are not connected to one another in series.
