Abstract

PURPOSE:To suppress generation of noise by a construction wherein a choke coil in a smoothing portion will never be song in an audio band area even by output voltage fluctuation. CONSTITUTION:An input d.c. voltage is applied to a switching portion I 16 via an oscillating portion 15, converted into the first high frequency pulse voltage, then converted into the second high frequency pulse voltage in a switching portion II 20 after passing through a high frequency transformer 17, rectifying portion 18 and smoothing portion I 19, and the converted high frequency pulse voltage is smoothed in a smoothing portion II 21, then applied to a load 23 as d.c. voltage through an output terminal 22. On the other hand, the output voltage fluctuation of the output terminal 22 resulted from the voltage fluctuation on the input 14 side or of the load 23 is given to an error amplifying portion 24, and the given voltage is compared with the standard voltage 25 so that the voltage fluctuation is transferred to the on and off control portion 26.
