Title: Electrical machine drive system and method

Abstract: An electrical machine drive system is simulated with a circuit simulator to model normal operation, fault modes and control strategies for electric motor based vehicles. The electrical machine drive system includes a DC power source model (102), an inverter model (104) and an electrical machine model (106). The system is modified through substitution of components or removal of components to simulate faults. Post-fault control strategies are implemented in a similar manner and simulated. The model and methods associated therewith reduce modeling complexity and reduce simulation time, permitting thorough design and analysis of electric motor based vehicles.
