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 inverter 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 inverter circuit.
For solving above-mentioned technical problem, lithium battery light storage electricity generation system inverter circuit of the present utility model comprises single-chip microcomputer and inverter circuit, described inverter circuit is connected with single-chip microcomputer input by temperature detecting unit, and described single-chip microcomputer output is connected with inverter circuit by PWM control unit; Described inverter circuit is connected with continuous input cell, and described inverter circuit is connected with single-chip microcomputer input by current/voltage detecting unit.
Further, filter unit is connected with between described inverter circuit and current/voltage detecting unit.
After adopting said structure, the PWM that single-chip microcomputer can realize inverter circuit switching tube controls, and realizes the transformation of direct current to alternating current, then by filter circuit filtering, just can obtain sinusoidal ac; 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 inverter circuit, and 3 is PWM control unit, and 4 is temperature detecting unit, and 5 is continuous input cell, and 6 is filter unit, and 7 is current/voltage detecting unit
Embodiment
As shown in Figure 1, lithium battery light storage electricity generation system inverter circuit of the present utility model comprises single-chip microcomputer 1 and inverter circuit 2, and described inverter circuit 2 is connected with single-chip microcomputer 1 input by temperature detecting unit 4.Described single-chip microcomputer 1 output is connected with inverter circuit 2 by PWM control unit 3; Described inverter circuit is connected with continuous input cell 5, and described inverter circuit is connected with single-chip microcomputer input by current/voltage detecting unit 7.Described inverter circuit is primarily of switching tube and transformer composition, and the size of the switching tube ON time scale and PWM duty ratio that adjust described inverter circuit with described single-chip microcomputer controls ac output voltage.
Further, filter unit 6 is connected with between described inverter circuit 2 and current/voltage detecting unit 7.
Operation principle of the present utility model is as follows: described single-chip microcomputer exports conducting and the shutoff that PWM ripple controls inverter circuit switching tube, direct current input is converted into and exchanges output, circuit filtering after filtering again, the alternating current that output harmonic wave content is less, the interchange namely in figure exports; By temperature sensing circuit sense switch pipe temperature, feed back to single-chip microcomputer, prevent that switching tube is overheated to be burnt out; Voltage detecting circuit detects the magnitude of voltage exchanging and export, then delivers to single-chip microcomputer by A/D sampling, and single-chip microcomputer exports control signal again after related operation, controls the stable of ac output voltage; 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.
