  We study analytical solutions of charged black holes and thermally charged
AdS with generalized warped factors in Einstein-Maxwell-Dilaton system. We
calculate Euclidean action for charged AdS and thermally charged AdS. The
actions in both backgrounds are regularized by the method of background
subtraction. The study of phase transition between charged black hole and
thermally charged AdS gives an insight to the confinement/deconfinement
transition. The plots of grand potential vs temperature and chemical potential
vs transition temperature are obtained.
