Description

L active circuits and the generator voltage controller of L activation

Technical field

The invention belongs to automotive generator electronic control technology field, more particularly to L active circuits and the generator of L activation Voltage regulator.

Background technology

With the development of automotive electronic technology, car generator voltage controller developed into from single function voltage regulator it is more Function voltage regulator, general single function voltage regulator are divided into the adjuster of discrete component composition and are made up of integrated chip The class of adjuster two；Multifunctional electric adjuster species is various, and its function of preliminary comprehensive statistics has：Basic regulatory function, IG activation Function, L activation function, excitation dutycycle feedback output FR functions or DFM functions, power tube overcurrent protection function, open-phase protection Function, shut down Duty ratio control function, phase terminal P control charging indicator light L functions, P terminal self-activations function, overtemperature prote Function, determine frequency adjustment of field excitation function, regulated value replacement function, load delay response (LRC) function, soft start (softstart) Function etc..

It is in addition very high to the reliability requirement of voltage regulator due to the particularity of automobile current generator working environment, this Just constrain in terms of two and printed with the use of ordinary electronic technical standard manufacture generator voltage controller high reliability product Card rate.

On the various such as way-train, car, minicar, general wagon, due to being restricted by technology, still largely Using single function voltage regulator, because its regulation is excessively simple, lacks the technological deficiencies such as protection, cause the generating of these vehicles Machine often due to there is output voltage rise, the technical problem such as output voltage is unstable, ripple coefficient is big in voltage regulator problem, Want solve these problems, it is considered that chip inlet need to be used as voltage regulator core, then be accompanied by associated peripheral circuits, The voltage regulator of generator required function is formed, but in fact the generator of many producers is equipped with the voltage of foreign chip manufacture Still the rate of being damaged occupies high phenomenon after adjuster, because chip inlet majority pressure voltage is in 40~60V, with state time generator factory The generator and Price List pressure voltage of business's production mismatch.Some using single-chip microcomputer voltage regulator its start voltage compared with Height, typically not less than 5V, and power that anti-interference is sensitive, is easy to procedural problem, its temperature tolerance and cost occur to power supply It is to be in a disadvantageous position.If redesign in addition, produce its design of high back-pressure voltage regulator chip and the test period is longer, cost It is very high and restricted by the technical merit such as automotive electronics high reliability, high temperature tolerance in terms of IC design and encapsulation, These comprehensive factors so that domestic and international automobile current generator manufacturer lowers one's standard or status using nine pipe generators or 11 pipe generators mostly, So coordinate single function voltage regulator, such generator is still largely used at present, but it reduce generator Combination property, as low speed power generation performance is poor, initial generating rotating speed is higher, its reliability is not also high.

If using multifunctional electric adjuster, the defects of low speed power generation performance difference can be overcome, and multi-functional regulation What device first had to solve is voltage regulator in KOEO states (Keyonengine off) excitation problem, and this just needs increase to know Other circuit and charging indicator light control circuit, even if it is also excessively complicated that general this circuit, which designs, in voltage regulator It is difficult to bear compared with multicomponent in the circuit board of limited small space allowed by housing, therefore only a small number of volumes are larger Voltage regulator can just assemble multifunctional electric adjuster, and this causes the voltage regulator function limitation of small size.

The L active circuits and phase P Terminal controls charging indicator light circuit of common existing generator voltage controller are such as Shown in Fig. 1, dotted line frame 100 represents the L active circuits and phase P Terminal control charging indicator light circuits of voltage regulator in figure, The circuit diagram of the regulation part of adjuster is omitted, the expression engine block of dotted line frame 200 part, wherein three-phase stator winding A, B, C exports direct current via after the rectification of diode D102~107 of rectifier bridge from B+.Charging indicator light is connected to voltage regulator L terminals, it is controlled by ignition switch IGSW.When ignition switch, resistance R101 is that indicator lamp controls power tube Q102 By grid voltage, power tube conducting, indicator lamp is lighted.Because power tube 103 is FET, it is indicator lamp 200mA's Saturation voltage drop is extremely low (typically in below 0.1V) under electric current, and wants to realize that L terminals activate voltage regulator, so low voltage It is difficult to, this magnitude of voltage itself is less than general triode emission knot conduction threshold, so triode can not be triggered.Such as Fruit carries out signal transacting and identification using comparator or operational amplifier, then be easily interfered generation mistake because signal is too low Sentence, therefore, the divider resistance R102 that connected between indicator lamp control output end and power tube drain electrode (the general resistor power compared with Greatly, volume is larger, organizes about in 10 Ω or so), it occupies larger area.Now divider resistance R102 upper ends are in indicator lamp Normal current potential when lighting to ensure that triode Q104 is reliably turned on, gives Q105 to provide in more than 0.8V by Q104 conducting Base current is the regulation part power supply (VC terminals) inside voltage regulator, therefore triode Q104, Q105 and its outer Enclose resistance and constitute " active circuit " for making voltage regulator enter excited state.The circuit is complex, it is larger to take volume, The circuit thick film chip board area ability 20mmX25mm of many voltage regulators, it is impossible to which carrying is compared with multicomponent, therefore the electricity Road application is very limited.

For these reasons so that function is less, nine pipe machines of limited performance and 11 pipe machines still in a large amount of productions and Using, but such generator needs additionally three Excitation Diodes of increase, is also the increase in cost and process takes, in nine pipes Machine, 11 pipe machines voltage regulator on there is terminal D+, that is, three single Excitation Diodes public negative pole as D + terminal, the end is simultaneously simultaneous to control charging indicator light, and only sampling D+ makes the load characteristic of voltage regulator poor, and when charging Either resistance becomes and then occurs that generator does not generate electricity or the rotating speed that initially generates electricity is too high greatly for indicator lamp open circuit, if but sampling more work( Can voltage regulator, then charging indicator light L terminals are independent controls, the terminal not with excitation positive pole power direct correlation.

Draw number of lines, simplified wiring line especially for voltage regulator is reduced, multifunctional electric adjuster is many only Need a L terminal line to activate the exciting current of adjuster, be referred to as " L activation ", primary is if member can be designed The less L active circuits of part, it will solve the problems, such as the complex circuit of multifunction electric generator voltage regulator, simplify circuit simultaneously Also improve reliability.

On the basis of realizing preferably and solving the activation of L terminals, voltage regulator function required for these vehicles can be with Relatively easily extend and cover：Basic regulatory function, IG activation function, L activation function, excitation dutycycle feedback output FR functions Or DFM functions, power tube overcurrent protection function, shut down Duty ratio control function, phase terminal P control charging indicator light L functions, P terminal self-activations function, overheat protection function, determine frequency excitation function etc., can also extend to and respond (LRC) with load delay Function, soft start (softstart) function etc..But prior art, which fails to realize, to be taken into account or has both above-mentioned most functions, can not Meet vehicle to safe power supply and the needs of quality supply, it is therefore necessary to relatively simple, the safe and reliable L of R ＆ D design circuit Active circuit and the generator voltage controller with L activation functions, so can also preferably solve Led charging indicator lights and ask Topic.

1. when ignition switch turns off, engine stop operation, generator does not also operate, now nothing on phase P terminals Voltage.Meanwhile charging indicator light power supply also ignited switch OFF, so triode Q1 and Q2 is cut without base current, two pipes Only.Activation terminal WK opens a way over the ground, and this causes triode Q4 base stages to obtain base current from resistance R11 and cause triode Q4 to lead It is logical, power tube grid potential is grounded, power tube cut-off.In this case, exciting current is cut off, because power tube grid supplies The general resistances of resistance R7 are larger (can be between 12K Ω~30K Ω), thus triode Q4 conducting electric currents it is minimum (1~ 0.4mA), power consumption is little, less than the shutdown power consumption of other modules of vehicle.Foregoing description is to connect electric power storage in voltage regulator positive pole Current situation under the circuit structure of pond positive pole, certainly, if this voltage regulator is still used for having three independent excitations In the generator with D+ terminals of diode, by D+ terminals come for Exciting Windings for Transverse Differential Protection power, then shutdown when due to D+ terminals without Voltage, triode Q4 is not turned under this state, there will not be faint power consumption electric current.

2. when vehicle ignition switch is connected, charging indicator light L terminals are connected with indicator lamp negative pole, and heater current is through triode Q1 emitter stages, resistance R1, R2 and triode Q2 emitter stages are both turned on to ground, two pipes, and wherein Q1 conductings are lit indicator lamp, Q2 Conducting ends triode Q4, and power tube Q12 obtains raster data model electricity when oscillating unit exports trigger pulse from resistance R4 Press and turn on, the logical exciting current of F terminations.

3. with generator operation, phase terminal P obtains the stator winding voltage signal from certain phase, by diode D9 one-way commutations and electric capacity C3 filtering become the direct current of relative smooth, and it plays the role of two aspects：

First, ending triode Q1, extinguish charging indicator light, second, the current potential continues as triode Q2 by resistance R1 Base current is provided, maintaining triode Q2 saturation conductions ends Q4, when output voltage is adopted higher than setting value (during such as 14.50V) Sample unit output voltage turns on threshold cell voltage-regulator diode D4 and triode Q11 emitter junction, turns on triode Q11, Power tube Q12 is turned off, and exciting current is cut off.Then, with power consumption, when voltage regulator sampling unit detects output When voltage falls below setting value (such as 14.50V), the voltage-regulator diode D4 of threshold cell ends, in oscillating unit output End triode Q11 under fixed frequency triggering negative edge burst pulse (low level is effective, is high-impedance state between non-low period) effect, power Pipe Q12 obtains gate drive voltage from resistance R7 and turned on, and F ends reclose exciting current.

When indicator light circuit is opened a way, being generated electricity by generator magnetic core remanent magnetism can make P points obtain induced potential, when the electricity Pressure reaches certain amplitude ends triode Q4 by triode Q2, and power tube can also turn on excitation, and this realizes phase certainly Function is activated, makes generator can be with self-generating under indicator light circuit open circuit conditions.

In addition, the generator voltage regulator circuit knot that there is IG and L to activate that Figure 11, which is embodiment of the present invention, to be provided Structure schematic diagram, it is possible to achieve IG activation, L activation, phase P activation.
