Abstract

PURPOSE:To protect a storage battery that backs up a smoothing capacitor from over discharge, by separating the storage battery from circuitry or connecting a battery when the storage battery is discharged continuously. CONSTITUTION:AC voltage received at an input terminal 1 is rectified through a triac 12 and a rectifier 11 then smoothed through a capacitor 14 to produce a predetermined voltage through a converting section 25. Droppage of AC voltage is detected through an AC voltage detecting section 26-3 while droppage of capacitor voltage is detected through a capacitor voltage detecting section 26-4. Upon droppage of both voltages, a switch 26-6 is turned ON through a logic circuit section 26-5 and a storage battery 26-2 is connected in parallel with the capacitor 14 in order to back up the capacitor 14. Upon detection of voltage drop of the storage battery 26-2, a voltage drop detecting section feeds a signal to the switch section 26-6 thus separating the storage battery 26-2 from the circuitry.
