As a novel series-parallel hybrid powertrain, the electric variable transmission (EVT) has gained much attention last years. With EVT, a power split function can be realized by changing its torque and speed in an electromagnetic way. Various machine types can be introduced into the concept of EVT. This paper will present a permanent magnet EVT (PM-EVT) with focus on its energetic modeling and control structure. Energetic Macroscopic Representation (EMR) is presented to be used to organize the connection between different elements of the PM-EVT. An inversion-based control is then deduced on the basis of EMR. Because the PM machines are more sensitive to operate in high speeds, field weakening is adopted. A simple energy management strategy has been developed in order to check the energetic modeling and the deduced control.
