Description
The utility model relates to a kind of D.C. regulated power supply.
Direct-flow voltage regulation source (or claiming voltage stabilizer) is the equipment of widespread usage in the electronic technology field.The landing of existing stabilized voltage supply self voltage is bigger.As CW7812 series integrated regulator, guaranteeing that minimum input voltage must not be lower than 16 volts under the technical indicator situation, promptly self voltage land must not less than 4 volts, and serial voltage stabilizer self voltage of CW7824 lands then must not be less than 6 volts.Press 1.5 amperes of calculating of output current, the power consumption of above-mentioned two kinds of voltage stabilizers is respectively 6 watts and 9 watts at least.As seen, existing common stabilized voltage supply power consumption is very big.For the stabilized voltage supply of big electric current output, its power consumption is more considerable.Moreover in the occasion that requires the landing of voltage stabilizer low-voltage, above-mentioned voltage stabilizer can not satisfy the needs of use.
The transistorized stabilized voltage supply of tandem type is formed as shown in Figure 1.The critical component of decision stabilized voltage supply self voltage landing size is to adjust element.Common adjustment element is to adopt 3 or 2 NPN transistor composition complex pipes, this complex pipe is equivalent to a NPN transistor, be not difficult to find out, when ignoring the other factors influence, as adjusting the stabilized voltage supply that element is formed, himself voltage landing minimum is respectively 2.1 volts and 1.4 volts (theoretical value) with this complex pipe.
The purpose of this utility model is a kind of D.C. regulated power supply with low self voltage drop of design, adopts the adjustment element of the new complex pipe that is connected to form by power transistor as stabilized voltage supply, reaches energy savings, the purpose of reduction use cost.
The energy-conservation D.C. regulated power supply of the utility model comprises:

The energy-conservation D.C. regulated power supply of the utility model, the equivalent triode of the complex pipe that employing NPN type silicon crystal triode and positive-negative-positive germanium crystal triode are formed as shown in Figure 3, its cut-in voltage Ube is low, only be 0.7 volt, as the adjustment element among Fig. 1, then the landing of self voltage of stabilized voltage supply is minimum can be 0.9 volt (theoretical value) with it.
Adopting the stabilized voltage supply of the utility model dress system, only is under 1 volt the situation in self voltage landing, still can operate as normal.Advantage and effect that this stabilized voltage supply is brought are as follows:
1, energy savings
From the theoretical value of above-mentioned two kinds of stabilized voltage supplys self pressure drop as can be seen, under same output current situation, the power consumption of energy-conservation stabilized voltage supply only is 1/2 of a common stabilized voltage supply, can reach energy-conservation 50% effect, the use of electronic equipment is extremely general on the human society, what wherein adopt linear stabilized power supply is the numeral that can't add up, if make the power supply of these equipment reach energy-conservation 50%, its social effect also is immeasurable.
2, reduce the raw materials consumption of stabilized voltage supply product
When adopting energy-conservation stabilized voltage supply, voltage stabilizer input dc power position is than low 2～4 volts of common stabilized voltage supply, thereby transformer secondary output provides the alternating voltage of rectification also can reduce, and the material consumption of transformer is reduced.
Because the heat dissipation amount of adjusting in the stabilized voltage supply on the element reduces, thereby the heat abstractor size is reduced, saved starting material, reduced the weight and the size of equipment.
3, enlarged the range of application of stabilized voltage supply
Some application scenarios requires self pressure drop of stabilized voltage supply should be very low, and at this moment common stabilized voltage supply is powerless.Energy-conservation stabilized voltage supply then can satisfy this requirement.For example, the application on automobile.The development of relevant technologies, the electronic equipment on the automobile is more and more, lives radio cassette player, automotive tv and the robot pilot that will use in the future, opertaing device etc. as the automobile electricity.Their power supply is provided by automobile storage battery.But when running car, generator charges to storage battery, though the effect of voltage regulator is arranged, voltage is always in fluctuation, and can introduce disturb electronic equipment by power supply.Generally, automobile through one section use, because the imbalance of voltage regulator, scope range of the fluctuation of voltage can substantially exceed the value of technical manual defined, China is 13.5～14.5 volts for the voltage-regulation scope of 12 volts of storage battery automobiles, the car that has under steam, when opening the throttle (the generator revolution is according to height), voltage can reach 16～18 volts, and this is a kind of harm to vehicle electronics.Between automobile storage battery and electronic equipment, install energy-conservation stabilized voltage supply additional, can discharge the interference of introducing by power supply, can provide stable, high-quality power supply to electronic equipment again.
