More Information
Summary:The utility model discloses an uninterrupted power source capable of preventing current impact, comprising a dc source used for changing electric supply into direct current. A lithium battery set composed of a plurality of lithium batteries is connected with an electric load of the dc source; a discharge control circuit and a charging control circuit in series connection are positioned between contacts of the dc source and the electric load and the lithium battery set; the discharge control circuit is used for conveying electric energy of the lithium battery set to the electric load; the charging control circuit is used for conveying electric energy of the dc source to the lithium battery set; a choked flow diode in a parallel connection with the charging control circuit is used for preventing current from the dc source from flowing to the lithium battery set under the discharge state of the lithium battery set; and a central processing unit controls connection and disconnection of the discharge control circu
