Junction temperature prediction method and apparatus for use in a power conversion module

摘要

A method and apparatus for predicting junction device temperature of at least a first switching device in a power conversion module that includes a plurality of switching devices, the method comprising the steps of, during switching activity, identifying at least one operating characteristic of the first switching device and solving an equation that uses the identified operating characteristic to predict the temperature of the first switching device where the equation solved is a function of the location of the first switching device with respect to the other switching devices in the plurality.
