Abstract :
A self-oscillating flyback converter circuit is presented for use as a switched-mode power supply giving a stabilized output DC voltage even if the input alternating voltage varies to a large extent. A detailed circuit analysis for the circuit and a trigger source for the driven supply in which the device operation is charted as the input voltage from zero to its rated value of 220 VAC are provided
