Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, patent content of the present invention is described in further detail.
Fig. 1 is the circuit diagram of a kind of charge in batteries voltage stabilizing circuit of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
In order to electromagnetic wave too high or too low in the current direction in stable electrical network and filtering circuit, the charging and voltage stabilizing circuit diagram of the present invention's design as shown in Figure 1.Wherein protective tube is connected with transformer, the output of transformer, and one end is connected with the positive pole of D3 and the negative pole of D1, and the other end is connected with the positive pole of D4 and the negative pole of D2.Diode D5 be connected to three-terminal voltage-stabilizing integrated chip IC Vin end and between+Vout holds.In addition, electric capacity C1 holds with the Vin of three-terminal voltage-stabilizing integrated chip IC and is connected, and the ADJ end of C2 and IC is connected.Resistance adopts adjustable resistance PR1 connect with two fixed resistance R1-R2, thus can the magnitude of voltage of effective control circuit output, at output connection electric capacity C3, mainly for stablizing of voltage in further control circuit, prevents the generation of refluence phenomenon.
Found by research circuit, the primary coil of transformer delivered to by the alternating current of 220V through protective tube from plug, and deliver to 4 diodes from the alternating voltage that secondary coil induces through about 9V.Diode symbol in circuit has one end of short-term to be called its negative pole (or negative electrode), has one end of triangle advance mark to be called its positive pole (or anode).The basic role of diode only allows electric current to flow to its negative pole (the direction flowing that namely can only indicate by triangle) from its positive pole, and do not allow to flow to positive pole from negative pole.By the circuit design of such as Fig. 1, no matter from transformer, in two lines out, that root voltage is high, and electric current and can only be flowed into the circuit on the right by D3 or D4, flowed back to by D1 or D2.Like this, from the circuit on the right, positive pole is all that one end that D3 with D4 is connected forever, and negative pole is that one end that D1 with D2 is connected forever.This is the principle of diode rectification.The Resolving probiems that diode changes alternating current direction, but its voltage swing is also in change.And capacitor have can the characteristic of storage of electrical energy, just in time can be used for addressing this problem.Charge in capacitor when voltage is higher, when voltage is lower just by capacitor to circuit supply.This process is called filtering.C1 in figure has been used for this work.
Vin end (3 pin) of circuit of three-terminal voltage-stabilizing integrated IC is delivered to through the filtered more stable direct current of C1.After the effect of this circuit of three-terminal voltage-stabilizing integrated IC is held and provided operating voltage primarily of Vin to it, it just can keep its+Vout to hold (2 pin) than the voltage height 1.25V of its ADJ end (1 pin).Therefore, we only need the voltage adjusting ADJ end with minimum electric current, just can obtain larger electric current at+Vout end and export, and voltage ratio ADJ end exceeds constant 1.25V.We can also change output voltage by the tap position adjusting PR1.So can expect, when tap upward sliding, output voltage will raise.In figure, the effect of C2 carries out slight filtering to the voltage of IC1 pin, to improve the quality of output voltage.In figure, the effect of D5 in time having fortuitous event to make the 3 pin voltage ratio 2 pin voltages of IC also low, prevents from having electric current to pour in down a chimney from C3 cause it to damage into IC.
Above-described embodiment does not limit the present invention in any way patent, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in the protection range of patent of the present invention.
