The project deals with an electromechanical converter for an electric continuously variable transmission (EVT) in a hybrid electric vehicle. This electromechanical converter consists of several electrical machines that are coupled in a mechanical and electromagnetic way. It has two mechanical ports (MP’s) and two electrical ports (EP’s). In the EVT in a hybrid electric vehicle, the two MP’s are the combustion engine on the one hand and the wheels on the other hand. The two EP’s are connected, via two power electronic converters (PECs), to the battery of the vehicle. The EVT replaces the gearbox, the clutch, the alternator and the starter motor used in a conventional vehicle.
