Abstract
PURPOSE: To change an output voltage into a rated constant voltage, by detecting the positive and negative voltage fluctuation in an output and regulating a control current for switching elements by using a control voltage corresponding to the fluctuation.
CONSTITUTION: A DC-DC converter comprising a pair of switching transistors Q1, Q2 and a transformer 1 is provided with a starting circuit including a transistor Q4. Zener diodes D5, D6 are coupled to the output terminals 5, 6 of an output rectification circuit 4 and to a voltage comparator 7 made of an integrated circuit. The bases of the switching transistors Q1, Q2 are controlled by the output of the voltage comparator 7 through a control transistor Q3. As a result, the output of the voltage comparator 7 is feedbacked to the control transistor Q3 when an output voltage changes due to the fluctuation in a load or an input voltage. Thus, the output voltage is stabilized to a level almost determined by the Zener voltages of the Zener diodes D5, D6.
