Description

Electronic controller

The utility model relates to a kind of electronic controller, particularly a kind of electronic controller of scalable silicon rectification generator.

Automobile is comparatively strict to the voltage control requirement of generator, overtension will cause the damage of electric equipment, brownout can make the charge in batteries deficiency, and the effect of voltage regulator for automobile is the control exciting curent, makes stable magnitude of voltage of generator output.For many years, voltage regulator for automobile adopts electromagnetic type mostly both at home and abroad, China's utility model patent number is 96208367.4 and 98238074.7 efficient automobile voltage regulator and automobile current generator voltage regulator, and mechanical governor FT221, FT121, rely on its internal relay to connect automatically and maintenance storage battery and generator field winding circuit communication, again can automatic cut-off loop when generator quits work, prevent that battery current from swinging to the field winding of generator, this installation cost height, volume is big, poor reliability, and environment for use requires high, life-span is short, and is shockproof.Humidity resistance is poor, need often carry out specialty adjustment, and power consumption is big, self-heating, and the contact chatter arcing is ablated easily.China's utility model patent number is 98237945.5 car electronic adjuster, can satisfy the adjuster regulation voltage and change requirement, improve functional reliability and sensitivity, but can not automatic cut-off loop when generator quits work, battery current is swung to the field winding of generator.

The purpose of this utility model is to propose a kind of electronic controller that can substitute mechanical governor FT221 fully that has the electronic controller advantage when can solve above-mentioned shortcoming.

The purpose of this utility model is achieved in that a kind of electronic controller, by triode T1, T2, T3, diode Z1, Z2, voltage-stabiliser tube DW, resistance R 1, R2 form, and are provided with the control section of photo resistance R3, light-emitting diode Z3, resistance R 4, diode Z4 composition between the base stage of T2 and negative pole.

The utility model has the advantages that structural design is new reasonable, easy to install, appearance looks elegant is generous, saves cost, regulation voltage precision height, and service free, contactless, the life-span is long, and is shockproof, humidity resistance good, uses the operational environment requirement low, and volume is little.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a circuit diagram of the present utility model;

Fig. 3 is the circuit diagram of the voltage regulator of mechanical-vibration type structure.

As Fig. 1, electronic controller shown in Figure 2, by triode T1, T2, T3, diode Z1, Z2, voltage-stabiliser tube DW, resistance R 1, R2 forms, T1, T2, the collector electrode of T3 connects positive pole, R1, the R2 series connection, two ends are just connecing respectively, negative pole, be connected in series DW and Z1 between the base stage of middle and T1, the emitter of T1 connects the base stage of T2, and the emitter of T2 connects the base stage of T3, the emitter sending and receiving motor field winding F of T3, the indirect Z2 of generator field winding F and negative pole, be provided with photo resistance R3. light-emitting diode Z3. resistance R 4 between the base stage of T2 and negative pole, the control section that diode Z4 forms, base stage and the negative pole of R3 two termination T2, Z3 one termination negative pole, another termination R4, another termination of R4 Z4, the other end sending and receiving motor center tap N of Z4, the indirect button positive pole of R4 and Z4.

When button is connected, light-emitting diode Z3 work, the resistance of photo resistance R3 diminishes, and IB2 has electric current to pass through, T2 work, IB3 has electric current to pass through, T3 work, generator has exciting curent IC3, generator for electricity generation.When button disconnected, because generator generates electricity, generator centre cap N offered light-emitting diode Z3 electric current, the adjuster operate as normal, when generator is not worked, light-emitting diode Z3 no current, the resistance of photo resistance R3 fades to maximum, IB3 is to minimum value, T2 ends, the IB3 no current, and T3 also ends, generator does not have exciting curent, IC3=0.Thereby prevent that battery current from swinging to the field winding F of generator.Because the output voltage (28V or 14V) of generator is higher than battery tension (24V or 12V), thus DW end, IB1=0, T1 ends.Though R1, R2 have little electric current to pass through, and are not more than 0.01A, can ignore.
