COMPACT ELECTRONIC POWER CONVERTER TO CONTROL AT LEAST ONE ELECTRIC MOTOR OF A VEHICLE

An electronic power converter to control at least one electric motor of a vehicle and having at least one group of power modules, each designed to power with an alternating current one single phase of the electric motor; two lateral plates, which are arranged on opposite sides of the group so as to form a pile; a hydraulic circuit, which is configured to cause a cooling liquid to circulate inside the plates; and a clamping system, which applies a clamping force to the pile in order to keep the pile compressed and has elastic elements, which are deformed in order to apply a compression force of elastic origin to the pile.
