Separately excited converter
A method in which a switching converter contains an independent oscillation circuit such as an oscillator, and the oscillation frequency of the primary side is transmitted to the secondary side via a transformer. Compared to self-oscillating converters, it offers greater flexibility in frequency, but has the disadvantage of requiring more components and resulting in a more complex circuit. Non-resonant converters include boost, buck, and buck-boost converters, as well as flyback and forward converters and push-pull converters. Resonant converters include current-resonant converters and voltage-resonant converters. Compared with self-oscillating converters, there are many types.
