Many beginners will wonder why there is no dc to dc transformer. There is no dc transformer in the transformer based on electromagnetic induction principle. Only the ac component of ac voltage or pulsating dc voltage can be transformed and transmitted by the coupling of the transformer's electro-magnetic-magnetoelectricity working process.
Therefore, transformer transformer can not be used for dc voltage conversion, because there is no inductive reactance in dc. If dc voltage conversion is necessary, it should also be converted into pulsating dc and then connected to the transformer. Secondary rectification is also needed in the transformer.
But if you have to lower the dc voltage, or raise the dc voltage, we can reduce the dc voltage and the oscillation and double the voltage rectification by using the pulse-width modulation rectifier filter, and then increase the voltage.
