Abstract
The invention provides an energy-saving cell phone charger, belonging to the application of electric technology in cell phone field. The charger comprises a plug enveloped with charging circuit, a lead, a cell phone charging interface. It is characterized in that: one end of the lead is connected to the plug enveloped with charging circuit; another end is connected to the cell phone charging interface. The advantage of this invention is that: (1) the energy-saving cell phone charger has no resistance, the useless power waste of the circuit itself is zero; (2) the simplest circuit, the least components, the highest reliability, the lowest cost, only a few penny, the smallest volume, the simplest manufacture; (3) due to compatibility of the entire circuit, it is beneficial to improve power factor in alternative power grid, and beneficial to absorb the pollution of the alternative power grid.
Description
Technical field
The present invention relates to a kind of charger, particularly the energy-saving linear mobile phone charger that uses in the daily life.
Background technology
Charger for mobile phone commonly used is made up of circuit such as voltage transformation, rectification, filtering, voltage stabilizings, generally will be with about 20 individual elements.Its weak point is that volume is big, the circuit complexity, and the cost height, conversion efficiency is low, has generally also used big power consumption resistance, and charging circuit itself is wanted power consumption, does not also have " charging " indication.
Summary of the invention
In order to overcome above-mentioned deficiency, the invention provides a kind of energy-saving linear mobile phone charger.It is made up of the plug that is packaged with charging circuit, lead, mobile phone charging interface.It is characterized in that
One end of described lead is connected with the ac power plug that is packaged with charging circuit, and the other end is connected with mobile phone charging interface.
The charging circuit of encapsulation is by the step-down current-limiting circuit in the described ac power plug, rectification circuit, and light-emitting diode and the transient protection that constitutes by electric capacity, filter circuit, insurance is formed; The ac input end of described rectification circuit is in series with the step-down current-limiting circuit that is made of electric capacity; The dc output end of described rectification circuit is parallel with light-emitting diode that indication " charges " and transient protection, filter capacitor; Between the dc output end and mobile phone charging interface of described rectification circuit, be in series with insurance.
Described rectification circuit is made up of the rectifier bridge that diode constitutes.
Compared with prior art, the invention has the beneficial effects as follows: (one), energy-saving linear mobile phone charger are without resistance, and the idle work power consumption of circuit itself is 0.(2), circuit is the simplest, used element is minimum, reliability is the highest, cost is minimum, only needs a few Mao Guo, the volume minimum is made the simplest.(3), since entire circuit be capacitive, help improving the power factor (PF) of AC network, pollution-free to AC network, help absorbing the pollution of AC network.
Description of drawings
Fig. 1 is the circuit theory diagrams of energy-saving linear mobile phone charger of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
Embodiments of the invention.
As shown in Figure 1, this energy-saving linear mobile phone charger circuit is by capacitor C 1, rectifier bridge, and transient protection, filter capacitor C2 and light-emitting diode, insurance is formed.Step-down current limiting capacitance C1 becomes low pressure output to alternating current 220V, obtains direct current after the rectification circuit rectification that rectifier bridge D1, D2, D3, D4 constitute, and charges the battery.In charging process, " charging " indicator light does not work, and useless power consumption is 0.When charged, " charging " indicator light is bright, and useless power consumption is 0.Therefore, the useless power consumption of this energy-saving linear mobile phone charger is 0.Insurance Z is as the protection battery of mobile phone.
