Embodiment
Most preferred embodiment of the present invention is such, a kind of energy-saving voltage adjuster, comprise box body, automatic trigger element, voltage control unit, wherein, at automatic trigger element of the preposition increase of existing voltage control unit, automatic trigger element is installed in the described box body, voltage control unit, described automatic trigger element connects the P terminal, automatically the trigger element output connects amplifying triode T by resistance R 1, amplifying triode T connects voltage control unit by R2, realize low exciting curent, low initial generating rotating speed, self-starting function, D+ end no pulse voltage, described voltage control unit connects the B+ terminal, the D+ terminal, the F terminal, the E terminal.The excitatory mode of the B+ terminal of described voltage control unit and D+ terminal is a direct current, and exciting curent is 15mA.The initial generating rotating speed of described automatic trigger element control is between 900～1200 r/min.Described voltage regulator is not having the signal that the automatic sampling of dynamo governor meeting P is ordered under the condition of indicator light excitatory automatically.
Described energy-saving voltage adjuster is applied to the light-emitting diode of various charging indicator lights or 0.25W or the incandescent lamp of 10W.
Operation principle: this novel practical voltage regulator is used terminal P, B+, D+, F, E, and when generator did not rotate, the P end did not have the signal of telecommunication, and P point trigger element is not worked, and adjuster is in holding state.After generator rotated, the P point had a voltage signal that sends by remanent magnetism, starts working after P point trigger element captures this voltage signal, opens adjuster, and the electric current of B+ flows on the D+ by switch element, thereby realized the purpose of DC pre-excitation.Be not equivalent to low level on the D+ during owing to generate electricity, and B+ is a high level, so indicator light is normally indicated, after generator was initiated electricity fully, the balance of voltage between D+ and B+ was so indicator light will extinguish.
Though need to prove that the voltage on the P point is alternating current, just be used to open adjuster, alternating current itself does not participate in excitatory in advance, so the D+ no pulse signal of telecommunication.
Because pre-exciting curent is to sample from B+, the pre-exciting curent of supply generator equals to flow to from B+ the electric current sum of the electric current on the D+ and the charging indicator light of flowing through, flow through like this charging indicator light electric current very little (15 mA) in addition do not have charging indicator light that exciting curent is provided, generator still has sufficient exciting curent, satisfy the generator normal power generation, thereby realize low exciting curent generator normal power generation and self-starting function.
The initial generating rotating speed of generator can be controlled by the sensitivity of P point trigger element, and the initial generating rotating speed of highly sensitive generator is just low, and the general initial generating rotating speed of calculating and test setting generator that passes through is between 900～1200 r/min.
The invention voltage regulator: extensively be suitable for various charging indicator lights (little light-emitting diode to 0.25W is greatly to the incandescent lamp of 10W), when less exciting curent (15mA) that provides or big exciting curent, generator still can normal power generation; Generator rotating speed≤the 1200r/min that initially generates electricity guarantees under the engine idle state that generator can normal power generation; Have self-starting function, no charging indicator light or charging indicator light burn out on the automobile, and generator still can normal power generation.
More than disclosed only be a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
