One Transistor Automatic Battery Charger Circuit

A very simple single transistor automatic battery charger circuit is described in this article, which uses just a single transistor for the voltage detection as well as for automatically disconnecting the battery from the supply when it gets fully charged. Circuit Operation As shown in the diagram we can see a straightforward configuration where a … Read moreOne Transistor Automatic Battery Charger Circuit

Self Regulating Battery Charger Circuit

The post explains how a neat little self regulating automatic battery charger circuit can be made using just two inexpensive transistors. How it Works As can be seen in the diagram, this auto-regulating battery charger circuit utilizes just two transistors for detecting the charging thresholds, and cuts off the process as soon as these limits … Read moreSelf Regulating Battery Charger Circuit
