Power electronics module

A power electronics apparatus, comprising:

• a first electrically-conductive element and a second electrically-conductive element, intended to be respectively at a first electrical potential and at a second electrical potential;
• a first power electronics component and a second power electronics component being respectively mounted on the first and second elements;
• and
• a first portion and a second portion of a heatsink being respectively mounted on the first conductive element and on the second conductive element so as to enable the transfer of calories from each power component towards the corresponding portion of the heatsink throughout the corresponding conductive element, said portions of the heatsink including a first end located on the side of said elements and a second end, opposite to the first end, the first conductive element and the first portion of the heatsink being electrically insulated from the second element and from the second portion of the heatsink, via an electrical insulator,
• wherein each portion of the heatsink includes a lateral face oriented in the direction of the other portion of the heatsink, the electrical insulator being accommodated between said lateral faces of said portions of the heatsink, said lateral faces diverging from each other in the direction of the second end.
