Self-Oscillating Flyback Converter

Description

SPICE simulation of a self oscillating flyback converter. This converter, also referred to as the ringing choke converter, is a low component-count circuit used in low power off-line application, since the control of the circuit can be implemented with a few discrete components without integrated control employed on conventional PWM flyback converter. The implementation of the control is done with a single transistor,a positive feedback winding and a resistor divider network.
