Description
Technical field
The utility model relates to power-supply device technical field, is specifically related to a kind of photovoltaic automatic charging topological structure.
Background technology
Along with the demand of the mankind to the energy is increasing and the minimizing of traditional energy, energy problem has been instant problem, and solar energy, as clean, non-polluting energy sources, has become the principal direction of modern energy development.
At solar energy from net electricity generation system, usually the direct current of a certain electric pressure is converted solar energy into for direct-flow electricity utilization apparatus by solar charging device, unnecessary energy storage is in storage battery, in order to using when lacking solar energy, in order to utilize solar energy as much as possible, all need to carry out maximal power tracing, improve the utilance of solar energy.Cause the ratio accounting for total storage battery sum damaged of storage battery premature deterioration quite large in addition because accumulator cell charging and discharging is unreasonable, quite important to the rational management of charging and discharging of storage battery.
Utility model content
Technical problem to be solved in the utility model is that providing a kind of forms simply, the photovoltaic automatic charging topological structure that practicality is good.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of photovoltaic automatic charging topological structure, comprise the first resistance R1, second resistance R2, first diode D1 and the first triode Q1, described first resistance R1 one end is connected to photovoltaic module cell panel positive pole PV+ and battery positive voltage BAT+ respectively, the first resistance R1 other end is connected to second resistance R2 one end, the described second resistance R2 other end is connected to photovoltaic module cell panel negative pole PV-, described first diode cathode is connected to photovoltaic module cell panel negative pole PV-, described first diode D1 positive terminal is connected to the first triode Q1 base stage, described first triode Q1 collector electrode is connected to battery terminal negative BAT-, described first triode Q grounded emitter.
Described first diode D1 is 12V voltage stabilizing didoe.
Operation principle: when morning the sun out time, voltage between PV+ and PV-progressively raises, by R1, R2 dividing potential drop, because the rated voltage of storage battery is 12V, D1 can adopt the voltage stabilizing didoe of 12V, when the voltage on R2 more than 12V time, Q1 lead to, at this time photovoltaic cell cell panel is charged a battery by Q1.
Come interim when at dusk, intensity of sunshine reduces gradually, the voltage drop between PV+ and PV-, and when R2 branch pressure voltage is lower than 12V, Q1 automatically shuts down, and stops charging a battery.Achieve like this and automatically storage battery is charged by PV cell voltage, meanwhile, possess PV cell anti-reverse connection function.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, achieves and is automatically charged to storage battery by PV cell voltage, meanwhile, possess PV cell anti-reverse connection function.
