Description
Technical field
The utility model relates to BUCK circuit engineering field, especially a kind of novel B UCK translation circuit.
Background technology
As everyone knows, due to the growing of oil price and the consideration based on problem of environmental pollution, the status of regenerative resource in electricity generation system promotes increasingly, particularly solar energy more and more receives concern both domestic and external and develops, although solar energy has pollution-free, noiselessness, the advantage such as inexhaustible, nexhaustible, but too can in power generation process, solar cell directly can not supply accumulators, one be because can not make full use of like this solar cell generate electricity can, two is harmful to storage battery.
Therefore, be necessary to provide a kind of BUCK translation circuit to realize the conversion of electric energy.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel B UCK translation circuit.
To achieve these goals, the utility model adopts following technical scheme:
A kind of novel B UCK translation circuit, it comprises solar panel, storage battery, controller, triode, field effect transistor and inductance coil, the base stage of described triode is connected with controller by the 3rd resistance, the collector electrode of described triode by the second resistance simultaneously with solar panel negative pole, the negative pole of storage battery is connected with the grid of field effect transistor, described field effect transistor source electrode is connected with the positive pole of solar panel by the first diode, the grid of described field effect transistor is connected with the positive pole of the first resistance with the first diode respectively by the second diode, the positive pole of described first diode is connected with the negative pole of solar panel and the negative pole of storage battery by the first electric capacity simultaneously, the drain electrode of described field effect transistor is connected with inductance coil, described field effect transistor is connected with the negative pole of solar panel and the negative pole of storage battery by the 3rd diode with between inductance coil simultaneously, described inductance coil position is connected with the positive pole of storage battery by the 4th diode, be connected with the negative pole of solar panel and the negative pole of storage battery by the second electric capacity between described inductance coil with the 4th diode simultaneously.
Preferably, described second diode is transient voltage suppressor diode.
Owing to have employed such scheme, the utility model, by the direct current signal that solar panel exports being transformed into by field effect transistor the square-wave signal with variable duty ratio, changes the equivalent load of solar panel array with this; Meanwhile, the second diode is transient voltage suppressor diode, realizes carrying out clamping protection to field effect transistor, prevents the voltage of field effect transistor more than 20V; Further, utilize the first electric capacity and the second electric capacity all to play filter action, its structure is simple, easy to operate, has very strong practicality.
Accompanying drawing explanation
Fig. 1 is the electrical block diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, a kind of novel B UCK translation circuit that the present embodiment provides, it comprises solar panel U2, storage battery U3, controller U1, triode Q2, field effect transistor Q1 and inductance coil L, the base stage of triode Q2 is connected with controller U1 by the 3rd resistance R3, the collector electrode of triode Q2 by the second resistance R2 simultaneously with solar panel U2 negative pole, the negative pole of storage battery U3 is connected with the grid of field effect transistor Q1, field effect transistor Q1 source electrode is connected with the positive pole of solar panel U2 by the first diode D1, the grid of field effect transistor Q1 is connected with the positive pole of the first diode D1 with the first resistance R1 respectively by the second diode D2, the positive pole of the first diode D1 is connected with the negative pole of solar panel U2 and the negative pole of storage battery U3 by the first electric capacity C1 simultaneously, the drain electrode of field effect transistor Q1 is connected with inductance coil L, be connected with the negative pole of solar panel U2 and the negative pole of storage battery U3 by the 3rd diode D3 between field effect transistor Q1 with inductance coil L simultaneously, inductance coil L is connected with the positive pole of storage battery U3 by the 4th diode D4, be connected with the negative pole of solar panel U2 and the negative pole of storage battery U3 by the second electric capacity C2 between inductance coil L with the 4th diode D4 simultaneously.The direct current signal that solar panel U2 exports is transformed into the square-wave signal with variable duty ratio by field effect transistor Q1 by this circuit; the equivalent load of solar panel U2 array is changed with this; the signal that controller U1 exports is used for driving field effect transistor after being driven by triode Q2; second diode D2 is transient voltage suppressor diode; it carries out clamping protection to field effect transistor, prevents the voltage of field effect transistor more than 20V.First diode D1 and the 4th diode D4 is " anti-reverse charging " diode, only have when solar panel U2 output voltage higher than DC input voitage, VD higher than could conducting during storage battery U3 input voltage, otherwise cut-off thus ensure the safe operation of circuit; Simultaneously the first electric capacity C1 of this circuit and the second electric capacity C2 all plays filter action.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
