The utility model has the advantages of higher load capacity and efficiency of the power and is especially suitable to be used in a situation where lower power is needed.
Description
Technical field
The utility model relates to power technology, particularly a kind of power supply circuits of reactance voltage dropping power supply.
Background technology
In small-power power, the reactance voltage dropping power supply is use always a kind of.Traditional supply power mode, load normally are connected in parallel on the power supply, and when several loads were worked simultaneously, load current heightened, even exceed the power supply load, make traditional small-power reactance voltage dropping power supply cisco unity malfunction.
The utility model content
Technical problem to be solved in the utility model is exactly the deficiency at existing small-power reactance voltage dropping power supply load capacity difference, and a kind of power supply circuits that improve the power source loads ability are provided.
The technical scheme that its technical problem that solves the utility model adopts is: separating load series-fed circuit, comprise power supply, load C, load A, load B, it is characterized in that: described power supply adopts the non-isolation type two-supply circuit, and described load C is powered by one group of power supply, and load A and load B series connection are on another group power supply.
The beneficial effects of the utility model are: series-fed is adopted in load, and the increase of load can not increase power supply load (electric current), has improved the power source loads ability.And two groups of power supplys have improved power-efficient respectively to electric.
Description of drawings
Fig. 1 is a conventional power source power supply form;
Fig. 2 is a circuit block diagram of the present utility model;
Fig. 3 is the power circuit principle figure that the utility model adopts;
Fig. 4 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail:
By conventional power source power supply form shown in Figure 1 as can be seen, load current is identical when supposing each loaded work piece, as each load R1, R2, when R3, R4 work simultaneously, the load current that requires power supply to provide is 4 times of single load current, and this is the shortcoming of conventional power source power supply form.
In the utility model power supply circuits block diagram shown in Figure 2, power circuit 1 provides two groups of power supply V+ and V-by one's own efforts, power supply V+ is used for the power supply of load C, power supply V-is used for the power supply of load A, load B, and load A, load B are connected on the power supply V-, the quantity load current that increases series load can not increase, and has been equivalent to improve the load capacity of power supply.
Fig. 3 shows the power circuit principle figure that the utility model adopts, and this power circuit comprises reduction voltage circuit, rectification circuit, voltage stabilizing circuit; Reduction voltage circuit is connected with resistance R 1 by the parallel circuits of capacitor C 3, resistance R 2 and is constituted, and rectification circuit is made of rectifier diode D1, rectifier diode D2, and voltage stabilizing circuit is made of voltage stabilizing didoe Z1, voltage stabilizing didoe Z2; Described rectifier diode D1, its positive pole connects the reduction voltage circuit output, and its negative pole connects voltage stabilizing didoe Z1 negative electrode, voltage stabilizing didoe Z1 plus earth, described rectifier diode D2, its negative pole connects the reduction voltage circuit output, its positive pole connects voltage stabilizing didoe Z2 anode, voltage stabilizing didoe Z2 minus earth; Rectifier diode D1 negative pole output V+ voltage, the anodal output of rectifier diode D2 V-voltage; Capacitor C 1, C2 in parallel with voltage stabilizing didoe Z1, Z2 among the figure are filter capacitor.
Circuit theory diagrams of the present utility model are seen Fig. 4.Load is adopted and is separated supply power mode among the figure, and V+ is used for the power supply of control circuit (load C that is equivalent to Fig. 2), and V-is used for the power supply (relay J 1, J2 are equivalent to load A, the load B of Fig. 2 respectively) of two relay J 1, J2.Z1, Z2, Z3 are voltage stabilizing didoe, play pressure stabilization function, the fly-wheel diode of Z2, Z3 double as relay in this example, and R3 is a current-limiting resistance.From the circuit form as can be seen, when controlled switch K1, K2 disconnect, two relay J 1, J2 are in the tandem working state, and the electric current that flows through on each relay is identical (can certainly be many series connection), increase load (relay) and do not increase power supply load (electric current).Another characteristics of the present utility model are: the control of relay is that the control by paralleling switch realizes.These are different with traditional tandem tap control, as in traditional power supply power supply form (as Fig. 1), adopt the control mode of this paralleling switch, and when switch closure, power supply is equivalent to short circuit, and this is unallowed on conventional power source.It is constant-current source that this supply power mode of the present utility model requires power supply, or is approximately constant-current source, and the non-isolation type two-supply circuit that the utility model adopts can be regarded constant-current source as within the specific limits.When K switch among Fig. 41, K2 were all closed, power supply of the present utility model also can operate as normal.This point is from the power circuit principle figure (Fig. 3) that the utility model adopts, and as can be seen, the V-power supply short circuit does not influence the operate as normal of power supply yet.In addition, under this powering mode, voltage stabilizing didoe Z2, Z3 consumed power not when switch closure, switch disconnects, and during loaded work piece, the power of the last consumption of voltage stabilizing didoe Z2, Z3 is also very little, and voltage stabilizing didoe Z2, Z3 can select low power tube for use.Circuit of the present utility model than traditional parallel operation form, under equal conditions, has improved the load capacity several times of power supply.
