Construction & Working
Use Required ampere Step down transformer for your target battery, here we have used 0-14V AC / 3 Amps Step down transformer and for AC to DC rectification we have used Bridge Rectifier module BR1010 which gives High efficient DC supply with high Current rating.
BR1010
12v 7ah Battery Charger Circuit Diagram Pdf Schematic
This Bridge Rectifier module will have four terminals, two for AC supply input noted with sign wave and two terminals for DC output noted with positive and negative sign.
C1 and C2 capacitors are performing as filter in this circuit then LED indicates the presence of DC power supply at the output. Connect the target Battery at the output to get charged.
