Description

The intelligent electric electronic voltage regulator

The utility model relates to voltage regulator, is the intelligent electric electronic voltage regulator that a kind of automobile, tractor use.

The voltage regulator that present automobile, tractor use, form by silicon rectification generator group, accumulator and separate piece, in recent years, the electronic voltage controller that loaded in mixture by integrated circuit and separate piece has also appearred, this regulator can play pressure stabilization function, but the bipolar transistor tube lifetime is short, inefficiency, and fault is many; Duty is not directly perceived, and no self-protection function can not in time be found fault, easily damage in case the short-circuit voltage regulator occurs, even sleeve and accumulator.

The purpose of this utility model provides a kind of intelligent electric electronic voltage regulator, to solve existing automobile, used with tractor electronic voltage controller life-span weak point, inefficiency; fault is many; duty is not directly perceived, and no self-protection function can not in time be found failure problems.

The purpose of this utility model is achieved in that this electronic voltage controller is by silicon rectification generator group, accumulator and IC ₁Integrated circuit constitutes, at IC ₁The 5th pin and positive source between be connected a voltage stabilizer, voltage stabilizer is by integrated circuit (IC) ₂With shunt capacitance C ₄, C ₅Form, be integrated circuit (IC) ₁Reference voltage is provided; In integrated circuit (IC) ₁The 3rd pin pass through resistance R ₁, dividing potential drop is connected with power switch, power switch is by integrated circuit (IC) ₃, resistance R ₂--R ₆, capacitor C ₃, C ₆Constitute with diode; IC ₃1 pin ground connection, 3 pin connect positive source, 2 pin are input end, 5 pin are output terminal sending and receiving motor magnetizing coil, 4 pin are diagnosis end; In integrated circuit (IC) ₁3 pin by dichromatic LED LED ₂, resistance R ₄Connect positive source, pass through resistance R ₅Connect power cathode and constitute display circuit; At IC ₁4 pin pass through resistance R ₃Connect positive source, by photoelectrical coupler ground connection, integrated circuit (IC) ₃4 pin pass through resistance R ₆Connect photoelectrical coupler, LED ₁Ground connection constitutes holding circuit.

Principle of work: automobile, tractor are when just starting, and the voltage of generator output is very low, and low-voltage switches point is with W ₁Expression, integrated circuit (IC) ₁2 pin voltages be lower than the reference voltage of 5 pin, this moment IC ₁3 pin output high level, through R ₁Current limliting adds to power switch circuit IC ₃2 pin on, make IC ₃3 pin and 5 pin between open-minded, so 5 pin output battery tension, alternator obtains exciting curent, thereby makes generator keep stable voltage output, when running up, generator output voltage raises fast, the shutdown point is with W ₂Expression, IC ₁6 pin voltages be higher than the reference voltage of 5 pin, IC ₁3 pin output low levels, add to IC ₃2 pin on, IC ₃3 pin and 5 pin between turn-off, the generator magnetizing coil does not have exciting curent to be passed through, at this moment, generator only depends on remanent magnetism to keep generating, generator output voltage descends gradually, works as IC ₁2 pin voltages IC when being lower than reference voltage ₃Open-minded, generator obtains exciting curent again, thereby output voltage is risen once more, and the voltage-regulation of carrying out repeatedly like this like this is in the scope that makes generator output voltage be stabilized in to adjust; IC ₃2 pin and ground between be connected with resistance R ₂, be parallel with electrochemical capacitor C ₃But the filtering higher hamonic wave is eliminated the wireless interference of medium wave; Work as IC ₁3 pin output high level the time, dichromatic LED sends red light, works as IC ₁3 pin output low levels the time, dichromatic LED sends green glow, intuitively display working condition; In case magnetizing coil burns short circuit, IC ₃4 pin conductings, through current-limiting resistance R ₆Give photoelectrical coupler, LED ₁Power supply, at this moment, the light emitting diode in the photoelectrical coupler is lighted, and light adds on the photodiode collector in the photoelectrical coupler, and the photodiode conducting makes IC ₁4 pin and ground short circuit, at this moment, IC ₁Reset, 3 pin output LOW voltages add to IC ₃2 pin on, make IC ₃3 pin and 5 pin turn-off, cut off the generator storage battery power supply, realize the shutdown protection.

This utility model compared with prior art has the following advantages: 1) power controlling is big, and be adapted to any negative pole and take subsides, 12 volts of battery tensions, the following silicon rectification generator of 1500W uses; 2) duty is directly perceived, is provided with two relay indicating lights, and during operate as normal, a pilot lamp can send ruddiness or green glow automatically, the another pilot lamp is a malfunction indicator lamp, and when breaking down, this lantern festival is sent dazzling ruddiness, realize warning function, cut off the accumulator circuit simultaneously, realize self-insurance; In case fault is got rid of, this regulator can recover operate as normal automatically; 3) generator is stable for the charging current that accumulator provides.
