Description

System for increasing direct voltage by a photovoltaic subsystem.

Description TECHNICAL FIELD The present invention refers to a system for increasing DC voltage.

BACKGROUND ART In many cases there is a need to convert a direct voltage of certain strength in terms of volts and amperes, to a larger direct voltage. The present invention system provides a good and efficient answer to this need.

DESCRIPTION OF THE DRAWINGS The intention of the drawings attached to the application is not to limit the scope of the invention and its application. The drawings are intended only to illustrate the invention and they constitute only one of its many possible implementations.

FIG. 1 schematically illustrates the system (100) (without the panels).

FIG. 2 schematically illustrates one double-sided photovoltaic panel (205).

FIG. 3 schematically illustrates the cover (203) with a few lines of LEDs (204).

FIG. 4 schematically illustrates a top view of the system (without the cover).

FIG. 5 illustrates two double-sided photovoltaic panels with a rod of LEDs.

THE INVENTION The main object of the present invention is to provide a system (100) for increasing DC voltage, mainly in situations when the user has a relatively small DC battery for example a battery of three volts and one ampere and he needs a twelve volts and three ampere DC voltage. The system (100) includes a photovoltaic subsystem (200) and a DC battery (300).

The photovoltaic subsystem (200) includes a light-tight casing (201) that includes an opening (202), a cover (203) that is designed to close the opening, a plurality of LEDs (204) that are intended to illuminate the interior of the light-tight casing, and a plurality of double-sided photovoltaic panels (205) that are designed to be set within the light-tight casing and to generate direct voltage from the light of the plurality of LEDs. The DC battery (300) supplies the electricity for lighting the plurality of LEDs for generating the increased direct voltage by the double-sided photovoltaic panels.

The thickness (205TH) of each double-sided photovoltaic panel should not exceed two centimeters, the gap (206) between each double-sided photovoltaic panel and an adjacent double-sided photovoltaic panel (205AD) should not exceed three centimeters, and the total area of the double-sided photovoltaic panels should greater than four times the inner surface area of the light-tight casing.

The goal of this structure of the photovoltaic subsystem (200) is to create a small light-tight casing volume inside which the LEDs will light up and which will include a relatively large area of photovoltaic cells. From the experiments that we performed, we discovered that the smaller the volume of the light-tight casing, the more voltage the photovoltaic cells produce. Experiments that were performed produced very good results, and the system (100) charged a car battery of twelves volts and three ampere by a three volts and one ampere DC battery. The system may include a rechargeable battery (400) that is designed to be charged by the photovoltaic subsystem, and may include a power inverter (500) for converting the DC voltage of the rechargeable battery or the DC generated voltage to AC voltage when needed.

The system (100) by experiments provides good results when the length (201L) and the width (201W) of the light-tight casing was about 50 cm and the height (201H) 1 cm, and inside the casing was vertically set about thirteen double-sided photovoltaic panel each one with two cm width and with gaps of two cm.

Positioning of the LEDs inside the casing: It is preferably to attach the LEDs to the cover, in a way that they light all or most of the surface area of the double-sided photovoltaic panels. Also, it is possible for the LEDs to be at the end of vertical bars, to place the LEDs inside the case really deep between the panels.

Figure 1 schematically illustrates the system (100) (without the panels), Figure schematically illustrates one double-sided photovoltaic panel (205), Figure schematically illustrates the cover (203) with a few lines of LEDs (204), and Figure schematically illustrates a top view of the system (without the cover). Figure illustrates two double-sided photovoltaic panels with a rod of LEDs.

The positioning many double-sided photovoltaic panel inside the casing of the system, about 25 units, provides an aggregate solar panel area of about 50 square meters in a box with dimensions of 0.5 X 0.5 X 1 meter, and gives a significant saving of space 200 times utilization compared to existing systems. In addition to that, the reducing of the illuminated space gives a high light intensity (close to the photovoltaic cells of the panels) that causes the solar panel to produce a high current 24/7 regardless of weather conditions including sunlight.

Abstract A system for increasing direct voltage that includes a photovoltaic subsystem that includes a light-tight casing that includes an opening, a cover for the opening, a plurality of LEDs to illuminate the interior of the casing, and a plurality of double- sided photovoltaic panels that are set within the casing and generate direct voltage from light of the LEDs, and a DC battery for lighting the LEDs. The thickness of each double-sided photovoltaic panel does not exceed two centimeters, the gap between each photovoltaic panel and an adjacent photovoltaic panel does not exceed three centimeters, and the total area of the double-sided photovoltaic panels is greater than four times the inner surface area of the casing. The system may include a rechargeable battery to be charged by the photovoltaic subsystem and a power inverter for converting the direct voltage of the rechargeable battery to AC voltage.
