Multilevel simulation tools for power converters

Various methods for simulating the large signal behavior of power converters are discussed. Multilevel simulation is the most efficient approach, combining the speed of behavioral circuit description with the accuracy of device models. Results for control optimization and converter loss reduction demonstrate this. Widespread use of the tools and the methodology discussed, however, depends on the availability of proper models for the various circuit components. The problem of accurate device modeling versus simulation speed is addressed, and an example of an efficient design analysis is shown.<
