There are two conditions Where We can Connect a Transformer to the DC
In this strategy, a pulsating DC to the basic side of a transformer. For this situation, the negative process resets the flux and the time necessary of voltage is zero in one complete process cycle which again supports resetting the flux in the winding. This idea is utilized in Switched-Mode Power Supply. Explore power electrical transformer
A transformer works just on an AC current. If DC is supplied, the primary of a transformer might begin to smoke. But, there is a mode where we can work a Transformer on D.C by putting a high-worth resistor in series with the essential of the transformer.

When the essential winding of transformers is to be associated with a DC supply, a high opposition is associated in series with the essential. This series resistance limits the essential currently to a secure DC value and hence stops primary from burning out.
that you don’t associate a transformers to the DC without a high resistance in series with the primary. Since there is no recurrence in DC and the impedance (Z) of the inductor is zero. On the off chance that you put Z = 0 in the I = V/Z, Current will be a lot higher. For example, the inductor goes about as a short out to the DC voltage and currents.
