Brief description of the drawings
Fig. 1 is the circuit diagram for calculating internal power supply modular circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, one kind calculating internal power supply modular circuit, including triode VT1, Resistance R1, electric capacity C1, diode D1, electric capacity C2 and triode VT3, resistance R1 one end difference connecting triode VT1 transmittings Pole, electric capacity C1, electric capacity C3 and power supply VCC, the electric capacity C3 other ends connect respectively the resistance R1 other ends, ground connection diode D1 negative poles and Triode VT2 base stages, triode VT2 colelctor electrode connecting triode VT1 base stages, triode VT1 colelctor electrodes connect electric capacity C1 respectively The other end, output end vo, resistance R2 and triode VT3 colelctor electrodes, the resistance R2 other ends connect grounding resistance R3 and three poles respectively Pipe VT3 base stages, triode VT3 emitter stages connect electric capacity C2, resistance R4 and triode VT2 emitter stages, the electric capacity C2 other ends respectively The connection resistance R4 other ends are simultaneously grounded;The diode D1 is voltage-regulator diode.
Referring to Fig. 1, parameter builds circuit as illustrated, power supply VCC voltages are 24V, under normal circumstances, output end vo electricity Press as 12V, it is assumed that the output voltage of output end vo increases suddenly for some reason, then triode VT3 base potentials also increase, Increase VT3 Vbe, VT3 Ib increases, VT3 emitter stages current potential rise, VT2 Vbe reduces, and VT2 base current reduces, VT2 collector current also reduces, and VT1 collector current also reduces, VT1 tube voltage drop Vce increases, so as to maintain output end Vo voltages keep constant;If the output voltage of output end vo reduces suddenly, situation is similar to the above, herein not in description;Electricity R1, electric capacity C3 and diode D1 composition RCD clamp circuits are hindered, in the case where power supply VCC voltage pulsations are weaker, circuit can be strengthened Stability, electric capacity C2 effect is to utilize its charging current, lifting triode VT2 and VT3 switching speed.
In summary, the utility model calculates internal power supply modular circuit and protection is effectively monitored to output end vo, makes Output end vo voltage keeps stable, and circuit structure is very simple, and cost is low, small volume, applied widely.
