In an HEVs an electric machine is used in parallel with a gasoline powered engine. The engine is used for providing the average power for driving, while the electrical machine assists during start-up, breaking and providing power at non-nominal operation speed of the engine. In other words, the engine is operating only at nominal rpm, where it is efficient. For all other speeds, the power from the electrical machine is added to the power from the engine. Modeling and simulation of Hybrid Electrical Vehicles is briefly discussed in this paper. The focus of this paper is on the power electronics and the control of the power electronics and electrical machine. Important are the modeling of the various components in the HEV, such as the mechanical drive train, electrical machine, power electronics and control. In the mechanical drive train a model for the power split, differential, shaft, and wheel inertia is required. The model for the electrical machines can either be a first order model for system behavior or can be based on FEM calculations in ANSYS. The model for the power electronics includes the non-linear switching behavior, to account for harmonics in the electrical machine. From the simulated field oriented control, the Embedded C-Code for implementation in a DSP or micro-controller is discussed.
