Description
Technical field
The utility model relates to the storage of a kind of lithium battery light electricity generation system, particularly lithium battery light-preserved system booster circuit.
Background technology
At present, China's photovoltaic generating system mainly direct current system, the electric energy sent by solar cell charges a battery, and storage battery is directly to load supplying, and this type of system configuration is simple, with low cost, but due to the difference (as 12V, 24V, 48V etc.) of load DC voltage, be difficult to standardization and the compatibility of the system that realizes, particularly civilian electric power, owing to being mostly AC load, be difficult to come into the market as commodity using the photo-voltaic power supply that direct current power is powered.In addition, photovoltaic generation realizes being incorporated into the power networks the most at last, exchanges the main flow that photovoltaic generating system will become photovoltaic generation.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of reliable and stable lithium battery light storage electricity generation system booster circuit.
For solving above-mentioned technical problem, lithium battery light storage electricity generation system booster circuit of the present utility model comprises single-chip microcomputer and DC-DC boost converter, described DC-DC boost converter is connected with single-chip microcomputer input by temperature detecting unit, and described single-chip microcomputer output is connected with DC-DC boost converter by PWM control unit; Described DC-DC boost converter is connected with continuous input cell, and described DC-DC boost converter is connected with single-chip microcomputer input by current/voltage detecting unit.
Further, rectification filtering unit is connected with between described DC-DC boost converter and current/voltage detecting unit.
After adopting said structure, the PWM that single-chip microcomputer can realize DC-DC conversion circuit switching tube controls, and realizes the transformation of direct current from low pressure to high pressure, namely realizes boosting, then by filter circuit filtering, just can obtain stable direct current and export; It is overheated to be prevented by temperature sensing circuit real time temperature measurement.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is single-chip microcomputer, 2 is DC-DC boost converter, and 3 is PWM control unit, and 4 is temperature detecting unit, and 5 is continuous input cell, and 6 is rectification filtering unit, and 7 is current/voltage detecting unit
Embodiment
As shown in Figure 1, lithium battery light storage electricity generation system booster circuit of the present utility model comprises single-chip microcomputer 1 and DC-DC boost converter 2, described DC-DC boost converter 2 is connected with single-chip microcomputer 1 input by temperature detecting unit 4, and described single-chip microcomputer 1 output is connected with DC-DC boost converter 2 by PWM control unit 3; Described DC-DC boost converter 2 is connected with continuous input cell 5, and described DC-DC boost converter 2 is connected with single-chip microcomputer input by current/voltage detecting unit 7.
Further, rectification filtering unit 6 is connected with between described DC-DC boost converter and current/voltage detecting unit.
Described single-chip microcomputer exports conducting and the shutoff that PWM ripple controls boost circuit switch pipe, make low-voltage direct input be converted into high voltage direct current to export, again through rectifying and wave-filtering, the direct current that output noise is little, voltage detecting circuit detects the magnitude of voltage that direct current exports, sampled by A/D again and deliver to single-chip microcomputer, when deviation appears in direct current, feedback loop will deliver to single-chip microcomputer this deviation, and single-chip microcomputer carries out the laggard line correlation of process computing and controls, eliminate deviation, realize stable output; By temperature sensing circuit sense switch pipe temperature, deliver to single-chip microcomputer, prevent that switching tube is overheated to be burnt out; Current detection circuit detects the current value exchanging and export, and deliver to single-chip microcomputer contrast, if current value is excessive, then carry out current limliting process, current value does not normally then process.
Although the foregoing describe embodiment of the present utility model; but those skilled in the art are to be understood that; these only illustrate; various changes or modifications can be made to present embodiment; and not deviating from principle and the essence of utility model, protection range of the present utility model is only defined by the appended claims.
