Abstract
The utility model provides a device for improving the voltage of a voltage-regulator tube and leading in temperature compensation. The device comprises a three-end voltage-regulator tube IC (Integrated Circuit); one end of the IC is connected with an input positive end +, and the other end of the IC is connected with an output positive end +; the common end of the IC is connected with an input negative end - and an output negative end through diodes D. According to the device provided by the utility model, the grounding end of the voltage-regulator tube is additionally provided with one diode, so that the voltage can be improved by about 0.7 V, and the temperature compensation of about minus 1.4d%FS/100 DEG C is brought about. Furthermore, the two diodes can be additionally arranged, so that the voltage of about 1.4 V can be improved, and the temperature compensation of about minus 2.9%FS/100 DEG C is brought about.
Description
Technical field
The utility model relates to a kind of temperature compensation means, relates in particular to a kind of device that improves the voltage of stabilivolt and introduce temperature compensation.
Background technology
The fixed stabilivolt of existing standard has several different voltage class, 12V, and 15V relatively commonly uses, if want 12.7V or 13.5V just to be not easy.The temperature coefficient of the elastic modulus of nearly all material all is negative in the world, that is to say when temperature raises all can deliquescing, and deflection strengthens, when sensor is used, the characteristic of bringing is+DS/DT, if can add in circuit that the compensation of one-DS/DT is of great use.
The utility model content
Technical problem underlying to be solved in the utility model is, overcome the defects that prior art exists, and provide a kind of device that improves the voltage of stabilivolt and introduce temperature compensation, its earth terminal at stabilivolt adds a diode can improve approximately 0.7V of voltage, and bring approximately-temperature compensation of 1.45%FS/100 degree C, can certainly add two diodes and improve approximately 1.4V of voltage, and bring approximately-temperature compensation of 2.9%FS/100 degree C.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of device that improves the voltage of stabilivolt and introduce temperature compensation is characterized in that, comprising: stabilivolt IC, the termination of IC input anode+, another termination output plus terminal of IC+, and the public end of IC through diode D with input negative terminal-be connected negative terminal-be connected.
The beneficial effects of the utility model are, its earth terminal at stabilivolt adds a diode can improve approximately 0.7V of voltage, and bring approximately-temperature compensation of 1.45%FS/100 degree C, can certainly add two diodes and improve approximately 1.4V of voltage, and bring approximately-temperature compensation of 2.9%FS/100 degree C.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model circuit diagram
Embodiment
Seeing also shown in Figure 1ly, is the utility model preferred embodiment, comprising: stabilivolt IC, the termination input anode of IC+, another termination output plus terminal of IC+, and the public end of IC through diode D with input negative terminal-be connected negative terminal-be connected.
In the present embodiment, the model that stabilivolt IC adopts is LM78L12, and the model that diode D adopts is 1N914.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
In sum, the utility model is on structural design, use practicality and cost benefit, meet industry development fully required, and the structure that discloses also is to have unprecedented innovative structure, have novelty, creativeness, practicality, the regulation that meets relevant new patent important document is therefore mention application in accordance with the law.
