ング素子をＯＮ・ＯＦＦ動作させて上記トランス
の出力巻線に生起される電圧を直流化して負荷に
電力を供給するスイツチング電源において、上記
巻線とは別に上記トランスに設けられた第３の巻
線を動作表示灯の駆動電圧源としたことを特徴と
するスイツチング電源。 In a switching power supply that supplies power to a load by converting the voltage generated in the output winding of the transformer into DC by turning ON/OFF a switching element connected in series with the input winding of the transformer, a switching element that is connected in series with the input winding of the transformer is turned on and off to convert the voltage generated in the output winding of the transformer into direct current to supply power to the load. A switching power supply characterized in that a third winding provided in the transformer is used as a drive voltage source for an operation indicator light.
