直流電源回図。 A battery that is normally in a charged state is connected to the input side of the voltage stabilization circuit of a constant voltage DC power supply circuit that rectifies the AC input and then supplies a stabilized constant voltage through the voltage stabilization circuit. In an uninterruptible DC power supply circuit, the voltage of the battery is compared with a constant reference voltage in parallel with the voltage stabilization circuit, and an output is provided that makes the next stage switching transistor conductive only when the voltage of the battery falls below the reference voltage. A voltage stabilizing circuit bypass circuit is additionally connected, which is operated by the generated voltage comparator and a relay that operates by the conduction of the transistor of the switching transistor and directly connects the battery to the DC output side of the voltage stabilizing circuit. An uninterruptible DC power supply circuit featuring:
