Design of the Intelligent Quick Charger

With the popularization of electronic equipment in daily life, more and more chargers come into our views. Especially with the development of smart devices and the charging demand of large capacity power supply, the intelligent quick charger has attracted more and more attention. In this paper, a new IGBT drive circuit for the problem existed in current chargers was designed. In view of the false over-current of chargers caused by the instability of the power grid or other factors, a new type of over-current detection protection circuit was devised.
