Abstract
The utility model relates to a power technology, in particular to an alternate and direct compound power. The utility model aims at the application range limitation of the prior AC/DC convertor and provides a device which can provide emergency supply for a portable device in the event that nonuse of the alternate power. The portable power supply device of the utility model comprises the AC/DC convertor which is arranged inside the shell and a direct current output terminal; the utility model is characterized in that the a charge battery and a DC/AC convertor are arranged inside the shell; the charge battery connects with the AC/DC convertor, and the charge battery connects with the direct current output terminal through DC/AC convertor. The utility model has advantages that the portable device can be supplied without alternate power supply, and is carry-home, easy for use and is suitable for the portable device in particular.
Description
Technical field
The utility model relates to power technology, particularly a kind of alternating current-direct current composite power source.
Background technology
Portable set, notebook computer, DV video camera, digital camera, mobile phone and MP3, MP4 etc. as commonly used generally adopt rechargeable battery powered.USB interface then is a kind of interface shape of standard, and present portable set is provided with USB interface more and more, both has been used for the signal connection end mouth, also can be used as the receiving end mouth.Portable set needs an AC/DC transducer, and alternating current is transformed into the direct current that equipment needs, and is used for the operate as normal or the battery charge of equipment.The AC/DC transducer of prior art, the scope of application is limited, if run into the situation that does not have alternating current or be not easy to use alternating current, the AC/DC transducer can't use.
The utility model content
The technical problem of all solutions of the utility model is exactly the limitation at the AC/DC transducer scope of application of prior art, provides a kind of and can provide the device of emergency power supply for portable set under the situation of not using alternating current.
The utility model solve the technical problem, and the technical scheme of employing is that portable power supply device comprises the AC/DC transducer that is installed in the housing, the dc output end mouth; It is characterized in that, be provided with rechargeable battery and DC/DC transducer in the described housing; Described rechargeable battery is connected with described AC/DC transducer, and described rechargeable battery is connected with described dc output end mouth by described DC/DC transducer.
The beneficial effects of the utility model are, AC/DC transducer and rechargeable battery are combined, and utilize the AC/DC transducer to charge for rechargeable battery at ordinary times, and under the case of emergency, rechargeable battery can provide power supply for portable set.Have and be easy to carry, characteristics easy to use are particularly suitable for portable set and use.
Description of drawings
Fig. 1 is the electrical block diagram of embodiment.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The utility model lumps together rechargeable battery, AC/DC transducer, DC/DC converter bank, constitutes the alternating current-direct current composite power source.
The technical solution of the utility model comprises the AC/DC transducer that is installed in the housing, the dc output end mouth; Be provided with rechargeable battery and DC/DC transducer in the described housing; Described rechargeable battery is connected with described AC/DC transducer, and described rechargeable battery is connected with described dc output end mouth by described DC/DC transducer;
Further, described dc output end mouth is a USB port;
Concrete, described AC/DC transducer and described DC/DC converter output voltage are standard USB voltage;
More specifically, described AC/DC transducer is a Switching Power Supply;
Further, also be provided with control circuit in the described housing; Described control circuit is connected with described Switching Power Supply and described rechargeable battery, is used for the output and the charging control of diverter switch power supply.
Embodiment
The portable power supply device that this is routine comprises the AC/DC transducer that is installed in the housing, rechargeable battery and DC/DC transducer, as shown in Figure 1.AC/DC transducer among the figure is made of Switching Power Supply, and it is little to have a volume, and the efficient height is convenient to integrated characteristics, is the first-selection of compact power.This routine dc output end mouth adopts standard USB port, and the output of Switching Power Supply and DC/DC transducer is set at standard USB voltage---5V, can with most of equipment interfaces, power.Also be provided with control circuit in this example, be used for the output of diverter switch power supply, when USB port has connected load, and it is normal to exchange input, the 5V voltage of Switching Power Supply output is electric, and this moment, rechargeable battery stopped charging, and the DC/DC transducer is in closed condition; If USB port does not have load, and it is normal to exchange input, and control circuit will provide constant-current constant-voltage charging for rechargeable battery; When USB port has connected load, and do not have the alternating current input, this moment, the DC/DC transducer was in running order, and rechargeable battery provides 5V normal voltage by the DC/DC transducer to USB port, is electric.Diode D1, D2 are isolating diode among the figure, can avoid Switching Power Supply and DC/DC transducer to influence each other.Because the DC/DC transducer can be operated in very wide input voltage range (general input voltage range at 1.2～36V, but rechargeable battery of the present utility model can be selected various lithium ion batteries, lithium polymer battery and various Ni-MH batteries etc. equal operate as normal).
