Self-excited converter

There is an independent oscillation circuit, such as an oscillator, inside the switching converter, and it transmits the oscillation frequency of the primary side to the secondary side via a transformer. Compared to a self-excited converter, it has the advantage of greater flexibility in frequency, but the disadvantage is that it requires more components and has a more complex circuit. Non-resonant converters include boost converters, buck converters, buck-boost converters, flyback converters, forward converters, and push-pull converters. Resonant converters include current resonant converters and voltage resonant converters. Compared to self-excited converters, there are more types.
