Abstract

The utility model discloses a diode voltage dropper, which utilizes a diode to positively drop voltage, and drops a DC current with higher voltage into a different DC current with lower voltage. The utility model can be manufactured as a fixed diode voltage dropper and a variable diode voltage dropper. When used, an adaptor having higher voltage or a dry battery serially connected in multiple sections is used to supply power for the voltage dropper, which can meet the demands of charge and discharge of diversified appliances. This not only saves expenditures for purchasing various adapters, but also can lessen the trouble of numerous belongings that is caused by taking a plurality of adaptors while traveling or being on a business trip, thus offering great convenience to people.

Description

The diode reducing transformer
Technical field
The utility model relates to a kind of voltage changer, particularly a kind of diode reducing transformer.
Background technology
Along with the development of society and improving constantly of living standard, the use of small household appliances such as mobile phone, digital camera, CD player, MP3, MP4, clock and watch, counter, remote controller and broadcast receiver is more and more, and these electrical equipment all need to use power supply, and wherein part is to use charge power supply or external power supply.These power source voltage are not quite similar, and 12V, 9V, 6V, 5V are arranged, and also have 4.2V, 3V, 2.4V, 1.5V and 1.2V etc., for electric power supply or the charging to these different voltages, be equipped with the adapter of various different voltages.If the voltage that electrical equipment requires does not conform to the voltage of adapter, then can not directly power or charge, can not directly be connected on the adapter of 12V as the broadcast receiver of 6V, the mobile phone lithium ion battery of 3.7V can not directly be used on the power supply of 9V.This brings many inconvenience to the user, and the user who particularly goes on business or travel need be with going up different adapters to satisfy the needs that mobile phone, MP3, MP4, digital camera etc. are powered or charged.If a direct current that can the direct current that voltage is higher converts different voltages to can be arranged, to be fit to the reducing transformer that different electrical equipment use, as 12V being fallen into 2V, 9V, 6V, 5V, 4.2V, 3V, 2.4V, 1.5V and 1.2V etc., that will bring convenience particularly for the people that go on business or travel to people.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of cost diode reducing transformer low, simple in structure, easy to use.
The technical scheme that its technical problem that solves the utility model adopts is:
The diode reducing transformer comprises reduction voltage circuit, the input termination DC power supply of reduction voltage circuit, and the load of output termination, described reduction voltage circuit is composed in series by a plurality of diodes.
Further improve as of the present utility model, be provided with the pressure regulation joint between described DC power supply and adjacent two diodes, the switch that is connected in output can be connected with described pressure regulation joint respectively, forms GSS Gear Select Switch.
The beneficial effects of the utility model are: the utility model utilizes the diode forward pressure drop, and the direct current of high voltage is reduced to low different direct current.It can make fixed diode reducing transformer, the middle or terminated line formation output interface from the diode string; For power supply or the charging needs that satisfy different electrical equipment, also can make type variable diode reducing transformer.Between DC power supply and adjacent two diodes, the pressure regulation joint is set, connects a switch of can be respectively connecting with described pressure regulation joint, form GSS Gear Select Switch at output.Be its power supply with the adapter of a high voltage or the dry cell of multi-section serial etc. during use, just can satisfy the power supply or the charging needs of different electrical equipment.So not only can save the expense of buying different adapters, and can alleviate and go on business or whilst on tour need carry a plurality of adapters, cause luggage various and the worry brought can bring convenience to people.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the fixed diode reducing transformer of a 2V circuit diagram;
Fig. 2 is the fixed diode reducing transformer of a 1V circuit diagram;
Fig. 3 is 11 grades of type variable diode reducing transformer circuit diagrams.
Embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3, the diode reducing transformer, comprise reduction voltage circuit, the input termination DC power supply of reduction voltage circuit, the load of output termination, described reduction voltage circuit is composed in series by a plurality of diodes, when the electric current forward passes through diode, diode can produce certain forward voltage drop, and this forward voltage drop is made up of two parts, and the junction voltage of PN junction and the electric current diode of flowing through is connected the pressure drop that resistance produces.For silicone tube, the junction voltage of PN junction is about 0.7V, and the junction voltage of the PN junction of germanium tube is about 0.3V, and this voltage is little with the magnitude relationship that flows through electric current.And diode connection resistance is several ohm of zero points, so the pressure drop that diode connection resistance produces is very little.Just can utilize the way of serial connection diode to reach the purpose of step-down according to this characteristic.The number of the diode of going here and there and model can be decided according to required pressure drop.
The utility model utilizes the diode forward pressure drop that the direct current of high voltage is reduced to low different direct current.Can make fixed diode reducing transformer, middle or terminated line formation output interface from the diode string.For power supply or the charging needs that satisfy different electrical equipment, also can make type variable diode reducing transformer.Between DC power supply and adjacent two diodes, the pressure regulation joint is set all.Connect a switch of can be respectively connecting with described pressure regulation joint at output, form GSS Gear Select Switch.Be its power supply with the adapter of a high voltage or the dry cell of multi-section serial etc. during use, just can satisfy the power supply or the charging needs of different electrical equipment.This not only can save the expense of buying different adapters, and can alleviate and go on business or whilst on tour need carry a plurality of adapters, causes luggage various and the worry brought brings convenience to people.
