1. A voltage converter comprising:
a power module comprising at least one controllable switch configured to switch and to perform a voltage conversion;
a heat sink, having an upper face opposite a lower face of the power module, configured to dissipate heat emitted by the power module, wherein the heat sink comprises at least one support projecting upward from the upper face of the heat sink; and
at least one resilient element, bearing on an upper face of the power module, configured to hold the power module in place relative to the heat sink, wherein each resilient element is rigidly and directly connected to the heat sink, and wherein each resilient element is attached to a top of the at least one support.
