Development of on-off duty cycle control with zero computational algorithm for CC-CV Li ion battery charger

Constant current constant voltage (CC-CV) lithium ions battery charger with new on off duty cycle control zero computational algorithm has been proposed in this paper. The techniques concise of simplify battery charger circuit and zero computational algorithm duty cycle control. The proposed circuit and technique then being tested with sort of experiment to prove it. Finally, the proposed technique is successfully doing the CC-CV stage swiftly and successfully charges the battery until 97% of its capacity in less than 3 hours' time.
