We review and compare three different models for the description of multi-band transport of charge carriers in semiconductors. They are based, respectively, 1) on the Floquet decomposition of the state space, 2) on the Wannier-Slater definition of envelope functions, 3) on the Kane model. The different mathematical and physical meaning of these models is discussed and compared.

Abstract
We review and compare three different models for the description of multi-band transport of charge carriers in semiconductors. They are based, respectively, 1) on the Floquet decomposition of the state space, 2) on the Wannier-Slater definition of envelope functions, 3) on the Kane model. The different mathematical and physical meaning of these models is discussed and compared.
