Forward Excitation Converter

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