Abstract

PURPOSE:To obtain an electric power supply generating circuit of FBT system which can accomplish the output stability the same as a DC-DC converter system, with a simple circuit constitution, by cancelling the fluctuation of pulse width due to the load variation at the secondary winding side of a flyback transformer. CONSTITUTION:One end of a primary winding 6 of a flyback transformer 5 is connected with a power supply applied terminal 4, and a pulse width set circuit consisting of a switching circuit 1, damper diode 2 and resonance capacitor 3 is connected to another end. A plurality of tap terminals are provided for two windings 7 of the transformer 5, and rectifying diodes 8, 11, 15, 18 and smoothing capacitors 9, 12, 16, 19 and loads 10, 13, 17, 20 are connected to the tap terminals. A reactance element 14 is connected between a diode 15 to a load 17 accompanying the load variance of a flyback power supply circuit and the diode 18 of the load 20, allowing to prevent the change in an equivalent distributed capacitance due to load change, and stable output is accomplished with a simple circuit constitution.
