Abstract

PURPOSE:To realize highly accurate operation with constant frequency and to reduce the number of parts, by controlling flyback voltage generated at a transformer, detecting it, and reflecting it to switching control. CONSTITUTION:A diode 8 and a variable impedance element 5 are connected in series to the 4th winding n4 of a transformer 10. An error amplifier 22 output is connected to the element 5. The amplifier 22 is given voltage between both terminals of a load 19 and reference voltage due to a constant voltage diode 3. A diode 6, a choke coil 11 and the load 19 are connected to the 2nd winding n2 in series. Diodes 6 and 7, and a capacitor 13 are connected to both terminals of the coil 11. The other terminal of the capacitor 13 is connected to the winding n2. A diode 9, a resistor 18, and a capacitor 14 are connected to the 5th winding n5. The both terminals of capacitor 14 are connected to the amplifier 22.
