Abstract

PURPOSE:To raise the input/output efficiency of the converter up to about 90% by rectifying the control current of the switching element in the switching output stage having a grounded-emitter construction so as to utilize it as the power source of the control circuit. CONSTITUTION:The switching output means is so arranged as an grounded emitter type that the drop in the voltage is lowered during the conduction of the switching element Q1 to reduce power loss. In addition, for example, the base current of switching output stage flows through the Zener diode D2 and the capacitor C2 by way of the transistor Q3. It is rectified to the constant voltage to be used as the power source of the control circuit comprising the astable multivibrator 1 and the monomulti-vibrator 2. said constitution can improve the input/output efficiency up to about 90%.
