Friends make the battery charging circuit in the attached picture, I input the 18 volt DC output of 13 volts DC button as he wrote in a pressure accumulator charge başlıyor.devr to explain normal charging is completed, the LED is supposed to burn, but for days despite having led yanmıyor.kullan I transformer 120 watt charger that I battery of 12 volts 4 amps .
circuit Description: LM338 is an adjustable voltage regulator. After connecting the battery circuit output "START" lm301 output offset voltage by pressing reset. Battery weak output circuit yüklenir.op-AMP 's (-) voltage at the end (+) is smaller than the input voltage. OP-AMP working as comparator 's output is positive. 2N2905 diode D2 is off and therefore kesimdedir.led. When charging is completed, the output circuit is no longer loaded. The output voltage rises. OP-AMP 's (-) voltage at the input (+) will be the potential to frame the comparator output to be greater than the input voltage. D2 diodes and transistors to pass messages. The LED lights to indicate that charging is complete.
