Abstract: The disclosure provides a transformer with an integrated inductor, including a magnetic core, a transformer winding and an inductor winding. The magnetic core comprises a magnetic yoke and magnetic columns connected to the magnetic yoke. The transformer winding is wound around at least one of the magnetic columns, and at least one transformer winding space is formed in the transformer winding. The inductor winding is at least partially accommodated in at least one magnetic yoke or at least one magnetic column of the magnetic core, so that the inductor winding penetrates through the transformer winding space formed by the transformer winding on a single magnetic column at most once, thereby decoupling the magnetic flux produced by the inductor winding from the magnetic flux produced by the transformer winding.
