Electric power module and method for making same

An electric power module comprising:

• at least one bar providing an equipotential connection made from an electrically conductive material;
• at least one electronic power component in direct contact with said conductive bar;
• a printed circuit board on which electronic components of the module having reduced heat dissipation are mounted, this board being arranged adjacent to said conductive bar with its top face disposed in a predetermined position relative to that of said conductive bar;
• at least one conductive bar through which a power current flows, underneath the printed circuit board and having at least one portion with a top face adjacent to said conductive bar and in a predetermined position relative to that of said conductive bar;
• said power component having contacts connected respectively to a printed circuit of said printed circuit board and to the top face of said portion of the power-conducting bar;
• and top and bottom layers made from a heat-cured insulating material covering said conductive bar, printed circuit board and power-conducting bar in their mutually adjacent zones in order to impart rigidity to the unit thus formed and to maintain the relative positions of said surfaces to guarantee the reliability and electrical continuity of the contacts of the power component.
