Abstract

PURPOSE: To lengthen the output holding time and also reduce the capacity of the smoothing capacitor, by using a back-up capacitor for storing the counter electromotive voltage of a transformer, which is much higher than the operating voltage, and holding the output voltage at the time of service interruption by means of its electric charge.
CONSTITUTION: A back-up capacitor C2 is charged with the counter electromotive voltage of the transformer 3, which is much higher than the operating voltage. And in case when the power supply is cut off at the time of service interruption, the output voltage is held by use of the electric charge with which the capacitor C2 has been filled. In this way, even when the operating voltage is small, the output holding time can be lengthened, and also the capacity of the smoothing capacitor C1 can be reduced.
