Abstract
Conventional core loss estimation methods exhibit limitations in dealing with important aspects of switching power converter applications such as different duty cycles, discontinuous-conduction-mode, variable switching frequency, or variable duty cycle operation. These limitations are particularly evident when trying to estimate boost inductor core loss in Power Factor Correction circuits. This paper first presents a core loss estimation method that addresses these limitations and then demonstrates an effective technique to estimate core losses in Power Factor Correction circuits. Finally, we show examples of how this method can be conveniently incorporated into simulation software to automate the core loss estimation process. The inductor models that are developed to facilitate this automatic core loss estimation and the approaches to implement the calculation in simulation software, especially a program called SIMPLIS, are also provided.
