Solar mobile phone charger

Abstract

The invention discloses a solar mobile phone charger. The solar mobile phone charger comprises a capacitor C1, a resistor R1, a triode VT1, a transformer T1, a diode VD1 and a triode VT2. One end of the capacitor C1 is connected with a 12V DC input, the resistor R1, a resistor R2, a coil Np of the transformer T1, the other end of the coil Np of the transformer T1 is connected with the other end ofthe resistor R2 and a collector electrode of the triode VT1, a base electrode of the triode VT1 is connected with the other end of the resistor R1, a resistor R3 and a collector electrode of the triode VT2, the other end of the resistor R3 is connected with a capacitor C2, and the other end of the capacitor C2 is connected with a coil Nb of the transformer T1. Compared with a common mobile phonecharger, the solar mobile phone charger is characterized in that energy is supplied from a solar cell panel, the solar mobile phone charger has a special charging protection circuit, the solar cell panel is placed on a place having sunlight, a convenient solar charging site can be provided for the mobile phone, the convenient solar charger can be supplemented with power almost in any place, and therefore communication freedom can be obtained.

Description

technical field [0001] The invention relates to a charger, in particular to a solar cell phone charger. Background technique [0002] With the increasingly serious environmental pollution, ecological destruction and resource depletion, countries around the world have implemented sustainable energy policies in recent years. Among them, photovoltaic power generation, which uses the sun to provide energy, has attracted the most attention. Photovoltaic power generation is safe, reliable, non-polluting, No need to consume fuel, no mechanical rotating parts, low failure rate, easy maintenance and other unique advantages, are being widely valued by all countries, forced by the increasingly serious global resource shortage and environmental pollution, making the development of the photovoltaic industry not only an economic issue , but also a problem of environmental protection and energy substitution.

[0002] With the increasingly serious environmental pollution, ecological destruction and resource depletion, countries around the world have implemented sustainable energy policies in recent years. Among them, photovoltaic power generation, which uses the sun to provide energy, has attracted the most attention. Photovoltaic power generation is safe, reliable, non-polluting, No need to consume fuel, no mechanical rotating parts, low failure rate, easy maintenance and other unique advantages, are being widely valued by all countries, forced by the increasingly serious global resource shortage and environmental pollution, making the development of the photovoltaic industry not only an economic issue , but also a problem of environmental protection and energy substitution. At present, photovoltaic cells are mainly used in the field of large-scale power generation connected to the grid and not connected to the grid, while there are very few application examples of consumer products. For example, there is no real and effective use of solar energy to charge cell phone batteries, so solar energy, as a non-polluting, easy-to-take green energy, is of great significance for improving the overall energy situation and environment of the earth if it can be applied to consumer products
