Description
Technical field
The utility model relates to a kind of voltage regulator for automobile, and especially a kind of single external connection module is realized the multi-purpose vehicle(MPV) voltage regulator of two kinds of functions.
Background technology
Consumer on the automobile mainly provides electricity consumption by automobile current generator, and regulator is exactly the generating whether core of control generator, is the indispensable inevitable ingredient of automobile generating system.
Along with the development of automobile industry, the electronic equipment of automobile accessories is required also can be increasingly high, and motor is as the basis of automobile electrical equipment, requisite will improving a lot.The function of motor realizes through regulator mainly that then this is just just higher to the requirement of multifunction regulator function aspects.
At present, each item major function of multifunctional series regulator mainly realizes by inheriting chip, but many times, a chips can not be integrated together all functions, and much other function needs external line module to realize.A kind of function of often every increase just needs a line module to realize.If will realize other two or more functions in a circuit, then need a lot of external circuits to realize.This has brought very big burden not only for the cost of circuit, simultaneously also can be higher to the requirement of technology.In addition, because the space of a regulator is limited, if increase too much external circuit, regulator can't be carried, simultaneously, also can make regulator become very too fat to move, the probability that risk occurs also can be higher.
Usually the multifunction regulator of band sensing function comprises six terminals; Be respectively B+, F, E, S, L, P; General regulator will be realized the two ends voltage regulation function, needs B+ and S terminal to meet Local-Sense (pin 6) and Remote-Sense (pin 8) respectively, just needs 2 detecting voltages; But this circuit does not have the emergency protection function, if the emergency protection function needs an external separately line module.And in order to reach the function of two ends pressure regulation, also need cut twice during production, need more manpower and manufacture craft.
Summary of the invention
The purpose of the utility model provides a kind of single external connection module to realize the multi-purpose vehicle(MPV) voltage regulator of two kinds of functions to technological weak point.This voltage regulator is the improvement on original technical foundation; Adopt simple external circuit module; Once cutting, two ends pressure regulation, some detecting, emergency protection have been realized simultaneously; And the cost of manufacture and the manufacture craft of having saved to a great extent, and circuit is simple, and reliability also realizes that with numerous external connection modules the regulator of functions improves a lot than tradition.
The utility model is realized through following technical scheme: a kind of single external connection module is realized the multi-purpose vehicle(MPV) voltage regulator of two kinds of functions; Comprise six function terminals P, B+, S, L, F, E; Normal pressure regulation IC line module and emergency protection function line module; It is characterized in that: the P utmost point of S termination one compound diode D2, the B+ end connects another P utmost point through a resistance R 14, and the public N utmost point of compound diode meets divider resistance R1 and R2; Pin 6 and pin 8 connect together and receive the tie point of R1 and R2; The C utmost point of the little signal triode of another termination of R2 and emergency protection regulating resistor R15, the E utmost point of triode and the other end ground connection of R15; The B utmost point of triode is received on the S end through resistance R 18.
The beneficial effect of the utility model is: state technical scheme owing to adopt, and the cost of manufacture and the manufacture craft of having saved to a great extent, and also circuit is simple, and reliability also improves a lot than the regulator of tradition with numerous external connection modules realization functions.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the circuit diagram that the single module of the utility model is realized the multi-purpose vehicle(MPV) voltage regulator of two kinds of functions.
Embodiment
With reference to shown in Figure 1; The utility model comprises six function terminals P, B+, S, L, F, E; Normal pressure regulation IC line module and emergency protection (Fail-safe) function line module; The P utmost point of S termination one compound diode D2, the B+ end connects another P utmost point through a resistance R 14, and the public N utmost point of compound diode meets divider resistance R1 and R2; Pin 6 and pin 8 connect together and receive the tie point of R1 and R2; The C utmost point of the little signal triode of another termination of R2 and emergency protection regulating resistor R15, the E utmost point of triode and the other end ground connection of R15; The B utmost point of triode is received on the S end through resistance R 18.
With when B+ normally is connected, the voltage of regulator is mainly brought in control by S at S end.This moment, Q3 can be reached also saturated by the current drives through R18, and the magnitude of voltage between the C-E of Q3 is almost nil, and with resistance R 15 short circuits; Because the B+ termination has resistance R 14, the voltage signal of S end can preferentially reach voltage, so the S end plays the effect of regulation voltage.After S end broke off, Q3 can close, and the electric current of the R2 that flows through must be through R15 to ground, and the B+ terminal voltage signal then arrives the detecting voltage point through R14 and R1, and the divider resistance of this moment becomes (R14+R1) and (R2+R15), mainly brings in the control pressure regulation by B+.The regulation voltage of the resistance relation decision B+ end of R14 and R15.On different product, difference that can be is as required confirmed the resistance of R14 and R15 to improve its precision, makes the pressure regulation value of B+ end that a definite scope arranged.During cutting, S is connected together with B+, the control killer voltage only need just once cut and can achieve the goal.When generator came off, because S termination storage battery, triode Q3 can drive always and hold at the B+ of generator output line; Pressure regulation this moment is mainly controlled by B+; Because divider resistance becomes R14+R1 and R2, regulation voltage can raise, but when being elevated to certain value; The voltage of detecting point can reach power tube and close voltage, makes the motor normal power generation.Boosted voltage mainly is that the ratio by R14 and R2 decides, but voltage is infinitely raise, and not being damaged of consumer on the protection car avoids burning the danger of car.
