This is a programmable current and voltage regulator circuit. It consist of a voltage regulator with external current limitation. The variable resistor R2 is forced by a constant current because of the fixed voltage of 2.77 V at the terminals … Continue reading →

To charge lead-acid batteries we can use this circuit that consist of a current-limited power supply and a flyback converter topology. Here is the schematic diagram of the circuit : Isolation and voltage input range flexibility are provided by the … Continue reading →

Switch mode circuits can implement the lead acid battery charger with a more efficient. It can be constructed using bq24105 battery charger controller. The bq24105 was originally designed to charge single-, two- or three-cell Li-polymer and Li-ion  battery packs. The … Continue reading →
