self-excited converter

In a switching converter, there is no independent oscillation circuit such as an oscillator, and oscillation is generated using the on/off operation of components like the primary side transistor and distributed capacitance, and the frequency is transmitted to the secondary side via a transformer. Compared to self-excited converters, this method has the advantage of fewer circuit components and simplification, but it also has the disadvantage of limited oscillation frequency flexibility. In non-resonant converters, there are insulated ringing choke converters. In resonant converters, there are partial resonance converters. Compared with self-excited converters, there are fewer types.
