Design of low power charger

Abstract: This paper introduces an automatic charger circuit for mobile phones and electric bicycles. It eliminates the complex IC circuit and its peripheral circuits, and can also complete the function of automatically charging the battery.

Keywords: battery; automatic charger; single-ended flyback; converter

In order to enable the chargers used in mobile phones, electric bicycles, etc. to realize the automatic charging function, most of them use various dedicated IC charger integrated circuits and various sampling circuits. This article introduces a circuit that can not only save the complex IC circuit and its peripheral circuits, but also realize the automatic charging function.
