Can transformers be used to step up DC circuits?

Can they be used? I know transformers work with the flux of the magnetic field and from what I recall, it was initially conceived using mechanisms to periodically, but at a constant rate, interrupt the current and thus create changes in flux. Can a regular transformer be used as is in a DC circuit or can I add a capacitor, creating a break in the circuit at specific frequencies?Can transformers be used to step up DC circuits?no you cant use a transformer to step down a dc signal, it might change the magnetic flux linking the coil initially, but later the output is zero. And the other thing is if you use a capacitor, it will block the dc signal, therefore there is no way that you can use a transformer in dc circuits.Can transformers be used to step up DC circuits?The only way, as far as I know, would be to build an oscillator which will convert the DC to AC, then use a transformer.

However, any increase in voltage will be accompanied by a decrease in current.
