The other end of the inductor is connected to the anode of a storage battery. The cathode of the storage battery is connected with the anode of the voltage stabilizing diode and then connected with the negative electrode of the solar cell panel. When positive and negative trigger signals are added to the gate pole of the thyristor capable of being turned off, the thyristor capable of being turned off can be automatically turned off, and the charging voltage of the storage battery is adjusted. The storage battery charging control circuit is simple in structure, low in cost and high in reliability.
Description
Technical field
The present invention relates to a kind of charging control circuit, particularly relate to storage battery charge control circuit in a kind of photovoltaic generating system.
Background technology
Solar energy is due to the feature such as not to the utmost of its recyclability, spatter property, use, and photovoltaic generation more and more comes into one's own and promotes.Storage battery is indispensable part in photovoltaic generating system as energy storage device, and electricity generation system operationally needs to carry out discharge and recharge to energy storage battery.In the photovoltaic array charging circuit of present low cost, photovoltaic array is directly to charge in batteries, the voltage exported due to photovoltaic array changes with the change in the external world, so when the output voltage of photovoltaic array is lower than battery tension, can not charge to storage battery.When the output voltage that array exports is higher, also may causes storage battery and overcharge, affect the life-span of storage battery, and the adjustment of charging voltage can not be realized in charging process; There is circuit complexity in the storage battery charge control circuit of perfect in shape and function, cost is high, generally also needs additional working power.
Summary of the invention
The object of this invention is to provide a kind of circuit structure simple, storage battery charge control circuit in a kind of photovoltaic generating system of the low cost of reliable, easy care.
Object of the present invention is achieved through the following technical solutions: storage battery charge control circuit in a kind of photovoltaic generating system, comprise storage battery charge control circuit, described battery charging circuit comprises electronic switching tube, be connected in series between solar panel and storage battery, described electronic switching tube is turn-off thyristor, when voltage higher than storage battery of the output voltage of solar panel, when the gate pole of turn-off thyristor has a direct impulse, between solar panel and storage battery, form charge circuit; Described battery charging circuit also comprises filter, and described filter is inductance; Described battery charging circuit also comprises clamper, and described clamper is voltage stabilizing didoe; The output voltage of described solar panel is connected with the anode of turn-off thyristor by after the first diode, one end of turn-off thyristor negative electrode connection inductance, after the other end of inductance connects the negative electrode of the second diode, is connected to the positive pole of storage battery.
Compared with prior art, the invention has the beneficial effects as follows: circuit structure is simple, easy to maintenance, reliable, while improving charge in batteries function, reduces production run cost.
