METHOD FOR PRODUCING AN ELECTRICAL TRANSFORMER BY ADDITIVE MANUFACTURING

Abstract

The invention relates to an additive manufacturing process for an electrical transformer (20) comprising: (i) - a step of depositing a powder bed comprising at least a first powder made of an electrically conductive material and a second powder made of an electrically insulating material, and (ii) - a step of locally melting the powder bed to obtain a layer of solidified material defining: a portion of a turn (53) of a primary winding (31) and/or a portion of a turn (54) of a secondary winding (32), and a portion of a body (57) of the electrical transformer (20), (iii) - a step of moving the build platform, - steps (i), (ii) and (iii) being repeated so as to obtain intertwined windings (31, 32) as well as a body (57) made of an electrically insulating material enabling the turns (53) of the primary winding (31) and the turns (32) to be electrically isolated from each other. (54) of the secondary winding (32). Figure 9
