The invention relates to an integrated transformer-inductor assembly (1) comprising a magnetic core (2) comprising a transformer column (23) around which transformer windings (3) are wound, inductor columns (22) around which inductor windings (4) are wound, and intermediate columns (24) constituting common magnetic elements of a magnetic circuit of the transformer windings (3) and magnetic circuits of the inductor windings. In order to provide decreased dimensions and reduced weight of such an assembly (1) as well as to ensure an efficient conduction and dissipation of heat generated in a core (2) of the assembly (1), the magnetic core (2) comprises at least two substantially identical component modules (21), wherein each component module (21) comprises a yoke (214) having a form of a plate comprising a rectangular part (2141) and two trapezoidal parts (2142) arranged symmetrically along a first longer side (21411) of the rectangular part (2141) and adjoining said first longer side of said rectangular part (2141) with longer bases (21421) thereof; a set of rectangular prism shaped component columns (211, 212, 213), parallel with each other and protruded on one side from the yoke (214) along a longitudinal axis (O) of the component module (21) which is perpendicular relative to the surface of the yoke (214), and including two outermost external component inductor columns (211) protruded from said rectangular part (2141) of the yoke (214); a central component transformer column (212); two component intermediate columns (213) having substantially the same length and disposed between the component inductor columns (211) and the component transformer column (212) and protruded from the rectangular part (2141) and the trapezoidal part (2142) of the yoke (214); wherein the second longer side (21412) of the rectangular part (2141) of theyoke (214) located on the side opposite relative to the trapezoidal parts (2142) of the yoke (214) and the internal lateral surfaces (2111, 2121, 2131) of all component columns (211, 212, 213) located at the side of this second longer side (21412) of the yoke (214) are coplanar with each other and form a contact plane (215); and wherein the external lateral surfaces (2133) of the intermediate columns (213) located on the opposite sides of these columns relative to the internal lateral surfaces (2131) thereof, are coplanar with shorter bases (21422) of the trapezoidal parts (2142) of the yoke (4); and wherein said component modules (21) are contacted with each other by means of contact frontal surfaces (2132) of the component intermediate columns (213) which are perpendicular relative to the longitudinal axis (O) of the module (21), and the longitudinal axes (O) of the modules (21) are positioned collinearly with each other; and wherein the component inductor columns (211) form the inductor columns (22), the component transformer columns (212) form the transformer column (23), and the component intermediate columns (213) form the intermediate columns (24).
