Abstract
The utility model relates to an intelligence voltage regulator for automobiles, comprising a sampling unit (1) which comprises a resistance voltage divider, a precise voltage-stabilizing integrated block voltage comparison element (2) and an intelligent horse power integrated block on-off element (3). The utility model is used for self-regulating electric generators of automobiles and charging for storage batteries. The voltage of the storage batteries keeps stable. The utility model has a plurality of functions of high regulation precision, short circuit protection, overheating protection, under-voltage protection, reverse connection prevention, etc.
Description
The utility model relates to a kind of structure of voltage regulator for automobile.
Voltage regulator for automobile is the automatic charge device of automotive battery, and its function is when the battery tension of automobile reduces, and feeds exciting current in the automobile current generator excitation coil, makes generator for electricity generation, and after rectification to battery charge.When battery tension is enough high, then cut off exciting current, the electrical generator generation outage.Introduced the structure of two kinds of voltage regulator for automobile in the 28th page～33 pages of " vehicle electrical system maintenance atlas " (People's Transportation Press in January, 1992 publish), a kind of is Electromagnetically vibrating, another kind is a transistor type, above-mentioned two kinds of voltage regulator for automobile exist voltage stability poor, (error is about rated voltage ± 5-10%), the contact easy burn-out of relay, shortcoming such as the overload capacity of switching transistor is relatively poor.
The purpose of this utility model is to propose the higher voltage regulator for automobile of a kind of degree of regulation.
This automobile intelligent voltage regulator comprises voltage sampling element, voltage comparing element and power switch component, the output termination voltage ratio of voltage sampling element is than the input end of element, the signal input part of the output termination power switch component of voltage comparing element, described voltage sampling element is the bleeder that two resistance are formed, the voltage comparing element is an integrated package of pressure-stabilizing, power switch component is a smart power switch integrated package, and the mouth of integrated package of pressure-stabilizing links to each other by a stabilivolt with the signal input part of smart power switch integrated package.
This automobile intelligent voltage regulator is owing to adopted integrated package of pressure-stabilizing to make the voltage comparing element, the input impedance height, and when reaching the critical voltage of integrated package of pressure-stabilizing, sampling voltage can transfer conducting to from ending rapidly, thereby control smart power switch integrated package is from conducting, transfer to and ending, vice versa, the degree of regulation height.The smart power switch integrated package also has functions such as short-circuit protection, overheating protection, under-voltage protection, and extremely strong anti-pulse ability, thereby the serviceability of this automobile intelligent voltage regulator is stable especially.
Accompanying drawing 2 is the use principle figure of this automobile intelligent voltage regulator.
As shown in Figure 1, (1) is the voltage sampling element, is in series by two resistance, is connected between power supply and the ground, and the junction a point of two resistance is mouth, receives the input end that the voltage comparing element is integrated package of pressure-stabilizing (2).The mouth b point of integrated package of pressure-stabilizing is by a stabilivolt D
1Receive the signal input part C point of smart power switch integrated package (3).The F point is the mouth of smart power switch integrated package, and the S point then is the power connection end, and the E point is a ground terminal, and (4) are dynamo field coil.When power line voltage is that battery tension is when low, the sampling voltage that a is ordered is lower, and when being lower than integrated package of pressure-stabilizing in-to-in reference voltage, integrated package of pressure-stabilizing ends, b point high potential, smart power switch integrated package (3) conducting, F point and S point are connected, and voltage output is arranged, dynamo field coil has electric current in (4), generator for electricity generation charges a battery, and battery tension raises gradually.When the voltage of ordering as a of sampling element (1) is elevated to and is higher than integrated package of pressure-stabilizing in-to-in reference voltage, the integrated package of pressure-stabilizing conducting, the b point is in active potential, by stabilivolt D
1Coupling, the current potential that c is ordered approaches zero, the smart power switch integrated package turn-offs immediately, its mouth F point is not communicated with power end S point, no-voltage is exported, the middle no current of dynamo field coil (4), electrical generator generation outage.
Can also meet a diode D between the mouth F of the smart power switch integrated package (3) of this automobile intelligent voltage regulator and the ground
3,, prevent that voltage regulator from damaging, and also can meet a diode D between the earthing pole of smart power switch integrated package and the ground in order to the self-excitation electric current that the electrical short circuit excitation coil produces
2Burn out the element of voltage regulator when being used for preventing the power supply reversal connection.
The using method of this as shown in Figure 2 automobile intelligent voltage regulator is identical with solid-state regulator, its terminals also are three of S, E, F, the S end is received the positive pole of storage battery (11) by a switch (9), the excitation coil (4) of F termination electrical generator, and E holds ground connection.Storage battery is powered to consumer (10), when voltage was low, electronic regulator was open-minded, and the F end has voltage output, electric current is arranged in the dynamo field coil, generator coil (7) outgoing current after rectifier (8) rectification, is supplied with battery charge, when battery tension is elevated to specified value, electronic regulator automatically shuts down, and F holds no-output, electrical generator no-output.
The integrated package of pressure-stabilizing of this automobile intelligent voltage regulator (2) can be selected accurate integrated package of pressure-stabilizing of TL431 or MC34061A overvoltage protection integrated package for use; smart power switch integrated package (3) can be selected BTS412 or BTS432 integrated package for use, all can obtain good effect.Voltage regulation accuracy can reach 1%; and cut off the electricity supply short-circuit protection, overheating protection, under-voltage protection and reverse connecting protection abilities such as cutting off the electricity supply automatically, can not open when input voltage is lower than 5V when device self temperature rise surpasses specified value when having the load end short circuit automatically.
