Abstract

PURPOSE:To remove a higher harmonic component generated from a transformer by inserting a low-pass filter between windings for the transformer. CONSTITUTION:Output pulses from a blocking oscillator using a switching transistor 7 as the center are stepped up by a step-up transformer 1, and smoothed by a capacitor 12 and fed to load. Output voltage is detected by a voltage detecting winding 4, and rectified and input to a control circuit 9. The control circuit 9 controls a transistor 5 so as to keep output voltage constant. A capacitor 10 is added in parallel with the voltage detecting winding 4, thus removing a higher harmonic component.
