The circuit compensation controller provided by the utility model is capable of protecting the compensating circuit from being burnt down.
Description
Technical field
The utility model relates to a kind of circuit compensation controller that can avoid compensating circuit to be burned.
Background technology
A kind of existing circuit compensation controller comprises a current sample load, and when the electric current in the circuit need to compensate, the resistance value of current sample load was less, and offset current can flow through compensating circuit within very short time; When circuit did not need to compensate, the resistance value of current sample load was larger, and the offset current that flows through compensating circuit is just very little.Wherein, when circuit need to compensate, because high electric current at transient flow overcompensation circuit, burns out compensating circuit easily.
The utility model content
The technical problem that the utility model mainly solves is that the compensating circuit of available circuit compensating controller is burned easily.
In order to solve the problems of the technologies described above, the utility model embodiment discloses a kind of circuit compensation controller, described circuit compensation controller comprises compensating circuit, resistance, current sample load and high level diode, one end of described resistance is connected with the high-pressure side of input voltage, the other end of described resistance is connected with an end of described current sample load, the other end of described current sample load is connected with the low-pressure end of input voltage, the negative electrode of described high level diode is connected with described compensating circuit, the anodic bonding of described high level diode is between described resistance and described current sample load, and the make-and-break voltage of described high level diode is lower than the minimum voltage that described compensating circuit is burned.
In a preferred embodiment of the present utility model, described current sample load is swept resistance.
Compared to prior art, circuit compensation controller of the present utility model can protect compensating circuit not to be burned.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the electrical block diagram of the utility model circuit compensation controller one preferred embodiment.
Embodiment
The below will be clearly and completely described the technical scheme among the utility model embodiment, and obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses a kind of circuit compensation controller, see also Fig. 1, described circuit compensation controller 1 comprises compensating circuit 10, current sample load R1, resistance R 2 and high level diode D1, one end of described resistance R 2 is connected with the high-pressure side 13 of input voltage V1, the other end of described resistance R 2 is connected with the end of described current sample load R1, the other end of described current sample load R1 is connected with the low-pressure end 14 of input voltage V1, the negative electrode 11 of described high level diode D1 is connected with described compensating circuit 10, the anode 12 of described high level diode D1 is connected between described resistance R 2 and the described current sample load R1, and the make-and-break voltage V2 of described high level diode D1 is lower than the minimum voltage that described compensating circuit is burned.When the voltage at high level diode D1 two ends was higher than its make-and-break voltage V2, described high level diode D1 was with breakdown, and therefore high electric current can not flow to described compensating circuit 10 again, thereby has protected described compensating circuit 10.
Wherein, described current sample load R1 is variable resistor R2, and for example described current sample load R1 is swept resistance or variable resistance box, and the high-pressure side 13 of described input voltage V1 and the voltage difference of low-pressure end 14 are preferably 15V.
In circuit compensation controller 1 of the present utility model, increased high level diode D1 between compensating circuit 10 and the current sample load R1, the voltage at described high level diode D1 two ends is designated as low level when being lower than its make-and-break voltage V2, very I is to ignore for its resistance, and this moment, described high level diode D1 was channel status.Be designated as high level when the voltage at described high level diode D1 two ends is higher than its make-and-break voltage V2, this moment, described high level diode D1 was off state, because make-and-break voltage V2 is lower than the minimum level that described compensating circuit 10 is burned, therefore.If resistance R 2 values of current sample load R1 are very little, can not pass through high level diode D1 just can burn out the high level of compensating circuit 10, thereby protect compensating circuit 10; On the other hand, if when needing the little electric current of compensate for slower, be applied to level on the high level diode D1 less than make-and-break voltage V2, high level diode D1 path, compensating circuit 10 can continue compensation.
In sum, circuit compensation controller of the present utility model can protect compensating circuit not to be burned.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model description to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
