| Abstract |
In energy harvesting technology, the United States and Europe are leading the technology development, but since the technology is in the stage of introduction around the world, it is a national investment to secure excellent harvesting-related technology through concentration of capabilities of domestic companies and to preoccupy the global market. The power level that can be used through energy harvesting technology is limited to low power of several watts or less, but in terms of energy cost that can be provided per unit time and unit area provided by energy harvested over a long period of several years or more even compared to the batteries currently in use, it can have a significant alternative meaning. Therefore, in this paper, a voltage coupling method near the lowest voltage of inverter operation was developed and converted as a study to increase the amount of solar power generation in the low sunlight section at sunrise and sunset through voltage tightening amplification adjustment and energy storage technology.
In addition, through the solar module voltage series/parallel variable connection conversion technology, the power generation time is extended even under the lowest inverter operating voltage to increase the amount of power generation. |
