Abstract
Average models of PWM regulated DC-to-DC power supplies are shown to be Euler-Lagrange systems. As such, passivity-based dynamical feedback controllers can be derived for the indirect stabilization of the average output voltage. The derived controllers are based on a suitable stabilizing "damping injection" scheme. The approach is applied to regulate DC-to-DC power converters of the "boost" and "buck-boost" types. The effectivity and robustness of the proposed duty ratio synthesis policies are tested, via computer simulations, on a stochastically perturbed model of a switched "boost" converter.Keywords
