Abstract	A systematic formalism for dealing withnonrelativistic time-dependent quantum Hamiltonians ispresented. The starting point is the Lewis andRiesenfeld invariant isospectral operator I(x, t). Wediscuss three examples: the generalized harmonicoscillator, the conformal oscillator, and the infinitesquare well with a moving boundary. We obtain the sameresults for the generalized harmonic oscillator as other approaches. In the case of the squarewell with a moving boundary, an effective interactionappears which seems to be due to the time dependence ofthe boundary. Consistency with the principle of minimal coupling and gauge invariance isobtained. Some interesting physical applications aresuggested.
