Abstract

A battery charger is a device used to recharge a battery so that it can be reused. This study aimed to design and construct a charger with selectable 12 V and 24 V outputs using a 10 A center-tapped transformer, a 10,000 µF/100 V electrolytic capacitor, a 20 A diode, a cooling fan, a switch, a fuse, and a volt-ampere meter. The experimental stages included planning, circuit design, component selection, assembly, and device testing. The transformer reduced the AC voltage, the diode rectified it, and the capacitor filtered the rectified voltage before it reached the output terminals. Tests covered the input voltage, both output modes, and charging under a battery load. The measurement results showed an input voltage of 221 V, a charger output voltage of 13.1 V, and a voltage of 25.69 V at the capacitor section. Measurements conducted during charging and under battery load also produced values of 12.1 V and 1.2 V. These findings show that the device can provide two output levels for basic charging. However, the tests did not yet evaluate current regulation performance, voltage ripple, temperature changes during operation, or the charging cut-off function when the battery was fully charged. Further development should add overcharge protection and automatic charging control.
