の巻数を設定したことを特徴とする電源回路。In a power supply circuit consisting of a transformer having a primary winding, a secondary winding that supplies the filament voltage of a fluorescent display tube, and a blocking oscillator circuit connected to the primary winding of the transformer, the input power supply voltage is set at a predetermined level. A power supply circuit characterized in that the number of turns of a transformer coil is set so that a blocking oscillation circuit stops oscillation when the voltage fluctuates.
