Description
Technical field
The application relates to a kind of lead acid accumulator public bus charging/discharging apparatus bus control circuit.
Background technology
In lead-acid storage battery production process, must relate to charge and discharge process, charging is generally all provided after the rectification of dry-type transformer isolated buck by 380 electrical networks.But the public bus charging/discharging apparatus electric discharge of lead acid accumulator does not possess back toward function when not being with inversion, the TV university part of so releasing re-uses to recharge battery, also has fraction just must be consumed by other approach.
Utility model content
The purpose of this utility model is to provide a kind of lead acid accumulator public bus charging/discharging apparatus bus control circuit, to overcome deficiency of the prior art.
For achieving the above object, the utility model provides following technical scheme:
The embodiment of the present application discloses a kind of lead acid accumulator public bus charging/discharging apparatus bus control circuit, comprising:
Busbar voltage sample circuit, gathers busbar voltage, when busbar voltage is higher than set point, then voltage is accessed nickel filament resistance board with consumed power;
Analog pid circuit;
IGBT manages;
Comparison circuit;
Triangle wave generating circuit, the voltage sampled is compared by comparison circuit and triangle wave generating circuit after described analog pid circuit smoothes, and exports PWM pulse width modulated wave, drives IGBT pipe to open and shutoff by drive circuit.
Preferably, in above-mentioned lead acid accumulator public bus charging/discharging apparatus bus control circuit, described drive circuit comprises IGBT driving chip and photoelectrical coupler, and described photoelectrical coupler is connected between described comparison circuit and IGBT driving chip.
Preferably, in above-mentioned lead acid accumulator public bus charging/discharging apparatus bus control circuit, between described busbar voltage sample circuit and analog pid circuit, sampled voltage match circuit is connected with.
Compared with prior art, the utility model has the advantage of: when the absorption energy (producing during electric discharge) on the utility model bus is greater than output energy (producing during charging), open discharge cell work, with form of thermal energy consumption, do not feed back electrical network, avoid polluting.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Figure 1 shows that the functional-block diagram of lead acid accumulator public bus charging/discharging apparatus bus control circuit in the utility model specific embodiment;
Figure 2 shows that the schematic diagram of busbar voltage and triangle wave.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be described in detail the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
Shown in ginseng Fig. 1, lead acid accumulator public bus charging/discharging apparatus bus control circuit, comprising:
Busbar voltage sample circuit, gathers busbar voltage, when busbar voltage is higher than set point, then voltage is accessed nickel filament resistance board with consumed power;
Analog pid circuit;
IGBT manages;
Comparison circuit;
Triangle wave generating circuit, the voltage sampled is compared by comparison circuit and triangle wave generating circuit after analog pid circuit smoothes, and exports PWM pulse width modulated wave, drives IGBT pipe to open and shutoff by drive circuit.
Further, drive circuit comprises IGBT driving chip and photoelectrical coupler, and photoelectrical coupler is connected between comparison circuit and IGBT driving chip.
Further, sampled voltage match circuit is connected with between busbar voltage sample circuit and analog pid circuit.
Circuit function characteristic: (as shown in Figure 2 no-output after busbar voltage and triangle wave) circuit does not work when sampling busbar voltage and being less than set point.When sampling bus circuit and exceeding set point, the triangular wave that the voltage sampled produces with triangular-wave generator after PID circuit smoothes compares, what export more afterwards is PWM pulse width modulated wave, IGBT is driven to open and shutoff by drive circuit, thus realize consuming the surplus power on bus, bus is controlled in set point.
In sum, when the absorption energy (producing during electric discharge) on bus is greater than output energy (producing during charging), opens discharge cell work, with form of thermal energy consumption, do not feed back electrical network, avoid polluting.
It should be noted that, in this article, the such as relational terms of first and second grades and so on is only used for an entity or operation to separate with another entity or operating space, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.And, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising described key element and also there is other identical element.
The above is only the embodiment of the application; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection range of the application.
