Abstract
The utility model discloses a constant voltage power supply based on integrated stabiliser, including first electric capacity, second electric capacity, first resistance, second resistance, integrated stabiliser and diode, the resistance of improvement second resistance just can obtain high output voltage. Under normal condition, the voltage that integrated stabiliser can bear is not high, and output voltage's the overwhelming majority is exerted on second resistance. Damage in order to prevent to start in the twinkling of an eye the overtension that integrated stabiliser itself bore, consequently insert the diode of a protection usefulness. Compared with the prior art, the utility model discloses main adopt integrated stabiliser be the core components and parts, integrated stabiliser small, low cost peripherally moreover only adopts five ordinary electric capacity resistance and diodes, can be able to bear or endure 150V and control highly compressed steady voltage, and convenient to use has the value of popularization and application.
Description
Technical field
This utility model relates to a kind of regulated power supply, particularly relates to a kind of regulated power supply based on integrated regulator.
Background technology
Along with society burns the wind, electrical equipment grows with each passing day.But the aging and lagging in development of electrical power distribution facility, and design the reasons such as bad and electricity shortage and cause the too low of terminal temperature difference voltage, the end of a thread user then often voltage higher.To electrical equipment particularly to the strict high and new technology of voltage request and precision equipment, just as not insuring.And manostat of the prior art uses the most thick and heavy components and parts such as transformator mostly, though can voltage stabilizing, but volume is relatively big, adds the volume of whole electronic device, and the small-sized manostat then high voltage performance of prior art is poor, accordingly, there exist room for improvement.
Utility model content
The purpose of this utility model is that provides a kind of regulated power supply based on integrated regulator to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
This utility model includes the first electric capacity, second electric capacity, first resistance, second resistance, integrated regulator and diode, first end of described first electric capacity simultaneously with the first end of described second resistance, as negative input and the cathode output end of regulated power supply after first end of described second electric capacity and earth terminal connection, second end of described first electric capacity be connected with the negative pole of the electrode input end of described integrated regulator and described diode simultaneously after as the electrode input end of regulated power supply, the negative input of described integrated regulator is connected with the first end of the second end of described second resistance and described first resistance simultaneously, second end of described first resistance simultaneously with the second end of described second electric capacity, as the cathode output end of regulated power supply after the outfan of described integrated regulator and the positive pole connection of described diode.
Specifically, the model of described integrated regulator be CW317, the first resistance R1 be 800 Ω, the second resistance R2 be 75k Ω, the first electric capacity C1 be 300 μ F, the second electric capacity C2 be 270 μ F, diode VD model be IN4001.
The beneficial effects of the utility model are:
This utility model is a kind of regulated power supply based on integrated regulator, compared with prior art, this utility model mainly uses integrated regulator to be core component, the volume of integrated regulator is little, with low cost, and periphery is only with five common capacitance resistances and diode, it is possible to the voltage stabilizing of resistance to about 150V high pressure, easy to use, there is the value of popularization and application.
Accompanying drawing explanation
Fig. 1 is circuit structure schematic diagram of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
nullAs shown in Figure 1: this utility model includes the first electric capacity C1、Second electric capacity C2、First resistance R1、Second resistance R2、Integrated regulator IC and diode VD，First end of described first electric capacity C1 simultaneously with first end of described second resistance R2、As negative input and the cathode output end of regulated power supply after first end of described second electric capacity C2 and earth terminal connection，Second end of described first electric capacity C1 be connected with the negative pole of the electrode input end of described integrated regulator IC and described diode VD simultaneously after as the electrode input end of regulated power supply，The negative input of described integrated regulator IC is connected with the first end of second end of described second resistance R2 and described first resistance R1 simultaneously，Second end of described first resistance R1 simultaneously with second end of described second electric capacity C2、As the cathode output end of regulated power supply after the outfan of described integrated regulator IC and the positive pole connection of described diode VD.
Specifically, the model of described integrated regulator IC be CW317, the first resistance R1 be 800 Ω, the second resistance R2 be 75k Ω, the first electric capacity C1 be 300 μ F, the second electric capacity C2 be 270 μ F, diode VD model be IN4001.
As shown in Figure 1, improve the resistance of the second resistance R2, just can obtain high output voltage.Under normal circumstances, the voltage that integrated regulator IC can bear is the highest, and the overwhelming majority of output voltage is consequently exerted on the second resistance R2.Damage to prevent from starting the overtension that bears of moment integrated regulator IC itself, therefore access the diode VD of a protection.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
