Abstract

This work investigates the effects of motor loads on power electronics building blocks. The work involves the development of computer tools to assess the impact of the switched reluctance motor loads on the drive power electronic building blocks. There are two methodologies that are followed in the characterization of the switched reluctance motor (SRM). Both approaches depend on a finite element model indirectly coupled with a state space realization of the electric machine. The models differ in the way the finite element FE and state space SS models are integrated. The first approach iterates between the FE and SS models until convergence occurs. The second approach runs the FE model and SS model independently. Both approaches are used to predict the normal behavior (fault free conditions) of the motor, the abnormal behavior (fault conditions), and the chopping operation of the motor. Motor losses are also determined for normal operation, chopping operation, and fault conditions.
