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

An electronic power converter (6) to control at least one electric motor (4) of a vehicle (1) and having at least one group (12) of power modules (11), each designed to power with an alternating current one single phase of the electric motor (4); two lateral plates (20), which are arranged on opposite sides of the group (12) so as to form a pile (17); a hydraulic circuit, which is configured to cause a cooling liquid to circulate inside the plates (20); and a clamping system (25), which applies a clamping force to the pile (17) in order to keep the pile (17) compressed and has elastic elements (26), which are deformed in order to apply a compression force of elastic origin to the pile (17).
