Abstract

In full hybrid electrical vehicles, two separate electric machines and two power inverters are required. One machine operates as a generator and the other works both as a generator and motor. The two electric machines are connected to an intelligent gearbox called planetary gear set together with engine. In this paper, a new machine - dual mechanical port (DMP) machine is proposed, which combines the functions of the two electric machines and the planetary gear set mentioned above. The structure and the dynamic model of DMP are introduced. A prototype is designed and analyzed by FEA. The control algorithms with the overall system operation performance are evaluated by computer simulation
