| Abstract |
To achieve optimal system weight and efficiency, the design of main components in an AC motor drive (electric machine and power converter) have to be optimized together. This is challenging considering the multi-physics and complex nature of its operation and interactions between the components. There are few papers that address a formal approach towards this design optimization for motor drives at a system level. This paper aims to fill this gap by presenting a fast and accurate system level motor drive model, for use in an optimization-based design approach. At a system level, the presented model is able to consider several aspects of machine-converter interactions. The model is also fully analytical and non-iterative, making it very computationally efficient. Further, a back-to-back motor-drive test setup is employed to experimentally verify the accuracy of the model and results are presented in this paper. |
