Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the present invention's do, but embodiments of the present invention are not limited thereto.
Embodiment 1:
The power circuit based on production management system as shown in Figure 1, comprise voltage input end in, Filter capacitance device and triode V2, described Filter capacitance device comprises triode V1, the collector electrode of described triode V2 is connected with the base stage of triode V1, the grounded emitter of described triode V2, the collector electrode of described triode V1 is connected on the negative pole of diode D1, the positive pole of described diode D1 is connected with voltage output end out by inductance L 1, the positive pole of described diode D1 is connected with ground capacity C3, the emitter of described triode V1 to be connected on voltage input end in and successively by resistance R3, voltage stabilizing didoe D2 is connected with voltage output end out, the base stage of described triode V2 is connected to the adjustable end of adjustable resistance R2, one end ground connection of described adjustable resistance R2 and the other end are connected with the common port of voltage stabilizing didoe D2 with resistance R3.
Described Filter capacitance device also comprises transformer T, one end ground connection on the described former limit of transformer T and the other end is connected on the collector electrode of triode V1, one end of described transformer T secondary to be connected with voltage input end in by electric capacity C1 and the other end is connected with the base stage of triode V1 by electric capacity C2, is connected with resistance R1 between the base stage of described triode V1 and emitter.
Described triode V1 is PNP type triode, and described triode V2 is NPN type triode.
The Standard resistance range of described resistance R2 is 200-1000 ohm.
The height of its output voltage of the power circuit of the present embodiment out is jointly determined by the puncture voltage of voltage stabilizing didoe D2 and adjustable resistance R2, and wherein, voltage stabilizing didoe D2 realizes the coarse adjustment to voltage, and adjustable resistance R2 realizes the fine tuning to voltage.Therefore, as long as change the resistance of voltage stabilizing didoe D2 or adjustment adjustable resistance R2, the various output voltage out of continuous variable can be obtained.The operation principle of this power circuit: form clearance-type oscillator by triode V1, transformer T, electric capacity C2, its off time, the height by output voltage controlled.When defeated people's voltage in accesses, triode V1, triode V2 conducting, defeated people's voltage in is added on transformer T by triode V1, and the electric current that passes through of its former limit linearly rule increases, and induce on secondary lower just on negative square-wave voltage; This induced voltage makes the further conducting of triode V1 by electric capacity C2, and the electric current on the former limit of transformer T also just increases further, and make transformer T and triode V1 form a hurried snowslide positive feedback between the two, triode V1 enters saturation condition rapidly.In the process, transformer T energy storage and electric capacity C2 start charging.When transformer T primary current reaches certain value, make the electric current on the former limit of transformer T can not continue again to increase because triode VI is saturated, make the induced voltage of secondary start gap changing inversely, the voltage acting in conjunction on this voltage and electric capacity C2 causes triode V1 collector current to decline.The same, a positive feedback avalanche process makes triode V1 end rapidly, and between the off period, diode D1 is started conducting and discharged by inductance L, electric capacity C3 by the energy once stored at pulse transformer between the triode VI conducting period of saturation.The principle of stabilized voltage of this power circuit: the voltage stabilizing process of circuit is realized by the intermittent time of change triode V1.When defeated people's voltage in raises or load current reduces, because the both end voltage U2 of voltage stabilizing didoe D2 is constant, therefore triode V2 base potential is reduced, the collector current of triode V2 reduces, and the deadline of triode V1 increases, the saturation conduction time reduces, so triode V1 ON time shortens, then reduced by transformer T primary current, the energy of storage reduces, the energy of release reduces, and output voltage out is reduced to former specified voltage stabilizing value.In like manner, when input voltage reduces or load current increases, its self-regulating process is contrary with upper.
