Zusammenfassung:	PURPOSE:To readily prevent the deflected excitation by detcting the width of the density of magnetic flux of a transformer or the product of a voltage and time, and controlling electronic switching elements by the detected result. CONSTITUTION:Transistors 1 and 2 are alternately conducted and turned OFF by the output which is obtained by the conversion of a power source E1 is supplied to the side of a secondary winding n2 of a transformer 4. The output voltage of a transformer 4 is detected between terminals 6 and 7 of a voltage detecting winding n3. Said detected voltage is applied to a linear inductor 11 via a rectifier 12. The voltage of a resistor 13 is inputted to a comparator 16 as a magnetic flux density detecting signal, and compared with a reference signal. The signal is sent to the control circuit inversion 3 from a terminal 8. The control circuit inversion 3 is controlled by said signal, and a gate signal is sent to the gates of the transistors 1 and 2.
