can d.c.transformer exist? if yes then what its max. rating?

Answer Posted / mahavir jagdev

You can have a DC transformer. But you will need a SCR to create a switched mode power supply to geat the fluctuating voltage, but it will be spkied surges at the other side which when smoothened out using capacitors will result into Dc on the secondary side too .... not a very economical idea as there will be too many losses.
