No, a DC transformer is not possible in the traditional sense. Here's why:
A transformer works based on electromagnetic induction, which requires a changing magnetic field to induce a voltage in the secondary coil. In an AC (alternating current) circuit, the current alternates between positive and negative cycles, creating a changing magnetic field that makes the transformer work. This is the key to how transformers function.
In a DC (direct current) circuit, the current flows in only one direction and remains constant. Since there’s no change in current flow, there’s no changing magnetic field, which means a traditional transformer cannot operate with DC.
However, there are ways to step up or step down DC voltages using other devices, such as **DC-DC converters**, which use components like inductors, capacitors, and transistors to switch and regulate the voltage. But these are different from the traditional transformer and use switching techniques to modify DC voltages.
