A transient behavioral model (TBM) for power converters

Abstract

This paper describes a new technique to model power converters. The resulting power converter model is referred to as a transient behavioral model (TBM). First, a simple buck power converter is used to demonstrate the TBM. A power converter called the dynamic voltage restorer is used to demonstrate a practical application of the TBM. It is shown that the TBM yields simulation results almost as accurate as the ideal switch model (ISM). At the same time, the TBM is computationally more efficient than the ISM. These features, coupled with the simplicity and the ease of implementation in a standard circuit simulator, make the TBM an attractive alternative to the ISM.
