Because of the many advantages of sealed lead acid batteries , has received a wide range of applications . However, sealed lead-acid battery charging technology does not seem to be valued, because of the way unreasonable charging the battery prematurely scrapped caused widespread . In view of this , I designed a two-stage constant pressure limiting a lead-acid battery charger.Charging principles of analysis:1 maintenance charge :When the battery voltage is low ( can be set to a default in the circuit 9V or less ) , the charger work in small current maintenance charge state, the working principle is U1C ⑨ feet ( inverting terminal ) potential is lower than ⑧ feet ( inverting terminal ) , U1C output low , T4 deadline . U1D 11 feet potential of about 0.18V. At this point the charging current of about 250mA ( constant current circuit consists of R14, U1D, T1B surrounding peripheral circuits , constant self- analysis of the principle of the reader ) .2 Fast charging :With the continued maintenance charge , the battery voltage is gradually increased , when the battery voltage exceeds 9V, into high-current fast charge charger mode , U1C ⑨ feet ( inverting terminal ) potential higher than ⑧ feet ( inverting terminal ), U1C output high potential , T4 conduction , U1D 11 feet potential of about 0.48V, the charger output approximately constant 1A current to the battery .(3) limit pressure float :When the battery is nearly fully charged , the charger automatically transferred under pressure limiting floating state ( pressure limiting float voltage is set to 13.8V, such as 6V batteries, the float voltage should be set to 6.9V), this time charging current will gradually decrease from the fast charging, fully charged until the battery is fully charging current of only 10 ~ 30mA, to supplement the battery self-discharge and loss of power.4 circuit protection and charging indicator :The circuit has a reverse polarity protection circuit, the D4, U1C, U1D, T1 and peripheral components when reverse battery charger output current limiting without incident . Charging is indicated by U1A, D7 and peripheral components , charging , D7 lit, the battery charger into the floating state , D7 goes out , charging is finished.5 slightly modify the circuit parameters can be adjusted circuit charging current , float voltage battery with different specifications to meet the needs .Note : CF = carbon film resistors ; MF = Metal film resistors ; MOF = metal oxide film resistors* Can be adjusted according to said element .Lead-acid battery charger circuit diagram shown in Fig.:

Published:2014/3/3 20:20:00 Author:lynne | Keyword: Infrared hood switch controller circuit,
Spend more and more kitchen range hood, it is the kitchen clean and a good helper. We have to press when using the power switch to turn on or off, when we hand full of greasy Would you expect this remarkable line trouble, always made the switch greasy. This circuit is the use of infrared light to control the switch as long as the palm of your hand too close to the switch stays on the line, like infrared faucets, very convenient and practical. Because it is close to using infrared, low power durable, energy-saving.
The circuit is mainly transmitted by infrared, receive, bistable switch and power circuit, as shown . R3, D3, C3 H to the receiving circuit to provide a stable 5V DC voltage. H quiescent current of 1 ~ 2mA. N4, N5 oscillation signal 32KHz , as amended by Q zoom out by the infrared emission tube D7. H receives the signal , high output, amplified by the C4 is coupled to N1 , N1 reverse output low, the flip -flop circuit , N3 high output, triac , exhaust fan work . If the received infrared signal H again , N2, N3 again flipped off SCR, hoods stopped . C5 N1 from interference and stable input level role , R4 is a pull-down resistor .Commissioning of high quality circuit board assembly , according to map production to succeed. Circuit board mounted on the wall switch in the original box . In the switch box cover drill two holes, hole distance of 2 cm, mounted at one end of the D7 sealed cylindrical hollow tube ( available toothpaste cap ), the translucent spout toward the hole, put another hole at the reception circuit H. After making a good integrated infrared transmitter and receiver tubes placed parallel to H ( H bald face and bald face parallel D7 ), internal definitely not light. Adjust the hand away from the D7 W about 15 to 20 cm can flip the circuit . (View)
