PROBLEM TO BE SOLVED: To miniaturize a power supply and an electronic apparatus using it. SOLUTION: A series connected unit, consisting of a diode 10 and a capacitor 11, is connected parallel to the primary winding 15 of a transformer 14. From a point between the diode 10 and the capacitor 11, resistors 8, 12 are connected to a first capacitor 9. Then, a point between the two resistors 8, 12 is connected to a first switching means 6. |
