A Novel Approach to Simulating Power Electronic System by Embedding Matlab Objects into Saber

Matlab/Simlink is a powerful tool for designing control algorithms for power electronic systems. We describe here a method for inserting a matlab-based controller directly into a Saber circuit simulation, which then yields a means to prove the viability of a comprehensive power electronic system design. This approach combines the best aspects of these two powerful tools, making full use of the advantages of each. The major procedure is to convert the MATLAB model to a Saber model. We describe in detail the process for doing that, and then illustrate the process with an example. The results obtained by such mixed model simulation are compared to those obtained by an all-native Saber simulation; numerical results were the same, but the execution time was about 50% longer with the embedded MATLAB objects.
