Abstract
An electronic circuit that accepts a variable DC voltage power source and converts it to a constant DC power source, the energy of which is either stored in a battery bank or sent out to DC loads or AC loads via a DC/AC conversion subsystem. The device capable of using solar, wind, geothermal, or hydroelectric energy sources.
Claims11
A portable electronic device, comprising:
- an input DC power source;
- a DC/DC voltage converter for converting the input power;
- a battery for storing the converted DC voltage;
- a DC/AC voltage converter;
- and
- an AC voltage outlet;
- and a plurality of solar panels for collecting solar radiation and converting it to become the source of the DC voltage;
- and
- a base for housing for foregoing components where the base has a first half and a second half hinged to fold the first and second halves into a closed and open position such that in the open position the solar panels are exposed and in the closed position the solar panels are not exposed in the manner of a suitcase,
- wherein the device converts solar radiation into AC power directly, without the aid of the battery, regardless of whether the battery is fully charged for storing electricity.
