For a particular class of backgrounds, equations of motion for string sigmamodels targeted in mutually dual Poisson-Lie groups are equivalent. Thisphenomenon is called the Poisson-Lie T-duality. On the level of thecorresponding string effective actions, the situation becomes more complicateddue to the presence of the dilaton field.  A novel approach to this problem using Levi-Civita connections on Courantalgebroids is presented. After the introduction of necessary geometrical tools,formulas for the Poisson-Lie T-dual dilaton fields are derived. This provides aversion of Poisson-Lie T-duality for string effective actions.
